I've tested those new kernels on my AMD P-II x4 965

with flags: arch=i386 ; arch=i386 -force64

there's no KP,
but I got stuck at the "No interval found for . Using 8000000" line

with flag: arch=x86_64

I got this KP

and wich kernel did u use for that ? bit more specific if u dont mind:-d

Can you boot into single user?
Then you could get the dmesg to me... I could use it to look up what goes wrong... :D
A new hope... :-d
EDIT: The second (the kp) is the classic 64bit AMD AppleACPIPlatform.kext panic...

I tested all those 5 kernels of yours & Anv's :)
NoAutopatch & Autopatch @ 32 & 64 bits compiled kernels

and I added them all into the iATKOS L1 disc

unfortunately, with: arch=i386 (-force64) -s
I still got stuck at the same line :'(

Try setting a scheduler with one of the following boot arguments.

traditional scheduler: sched=traditional
traditional scheduler with pset runqueue: sched=traditional_with_pset_runqueue
proto scheduler: sched=proto
grrr scheduler: sched=grrr
fixed priority scheduler: sched=fixedpriority
fixed priority scheduler with pset runqueue: sched=fixedpriority_with_pset_runqueue

Only use one and please test all to see if there is a difference.
These control how the processor schedules instructions.

On AMD you may also want to use boot argument npci=0x2000

Still investigating for the interval lines... ;)
EDIT: Oh yeah... are you booting from a DVD? Try using an USB boot... (may be worth trying)
Also grep for the string "No interval found" in all the .kext files with the following command:
grep -E "No interval found" /System/Library/Extensions/*.kext/Contents/MacOS/* /System/Library/Extensions/*.kext/*
Tell me if one matches...

Pthread support ABORTS when sync kernel primitives misused
No interval found for . Using 8000000

Looks like we need to compare the log with the vanilla dmesg if these messages appears

I saw this one appearing on my Intel with DP1 too: Pthread support ABORTS when sync kernel primitives misused
But No interval found for is not part of the kernel... either is coming from an app or coming from a kext...
Still investigating...
EDIT: Can't find it anywhere in DP1... don't have GM so can't check...
Did changing the scheduler change anything?
How about booting the installed product? This is the install DVD, right?
EDIT2: Did you patch /usr/lib/dyld and /usr/lib/libSystem.B.dylib with amd_insn_patcher (the new one for Lion)? It is needed for 32bit support under 64bit...

K did some intence testing with an installed system (cloned from my MBP when it came out in Juli 10.7.0)

only the kexts i used from SL

Disabler ,NULLPower, FakeSMC, rest is via DSDT

Bootloader i tried were cparm boot(latest) and Chameleon Rev1684

with all kernels and with none i came close to see a verbose mode sadly

tried all scheduler arguments as boot args gave me instant reboots too (on all)

all important bootflags were tested aswell offcourse

:'(

Got one match, 10.7.0 Installer Stick

For 32 Bits: the new amd_insn_patcher gives me on both dyld and libSystem.B.dylib:
