Long boot time, light blue screen

i am using iDeneb 1.5.1 with Qoopz Kernel. I have already tried with all other kernels, but it works best with Qoopz.
My problem:

If i boot in safe mode by -x everything works normal and system boots in about 30secs.
If i want boot normally, it stucks about 5 minutes at
IOKitWaitQuiet timed out waiting to write kernel symbols
and
InterfaceNamer: timed out waiting for IOKit to quiesce

Then it boots to a light blue screen, the one that is shown before the system is completely startet. Normally you can only see this screen for some seconds.
This light blue screen stays also for about 5 minutes, then the system is booted completely.
Changing bios options about SATA (AHCI, IDE, ...) or Energy options like ACPI etc.

I have already tried some other Versions of OSx86 like Kalyway, iAktos, iPC, Leo4All, ... but iDeneb is the one that works best.

My specs:
AMD Phenom X4 (cpus=1 not needed, makes no difference)
2GB DDR2 800
Gigabyte GA-MA78G DS3H rev2
AMD 780G + SB700 Chipset
ATi Radeon HD4870
Drivers for all components are installed.
