[Installation problem] XPS 420 iAtkos 10.5.5

[innervision]

Hey all,

I've been able to install 10.5.5 on my XPS 420, but it doesn't actually boot into the OS successfully. It just hangs at the grey Apple logo until I'm forced to restart.

System specs:
Processor: Intel Core 2 Duo E8400
Video: ATI Radeon 3870
Audio: Intel 82801I HD Audio Controller / ATI Radeon HD 3870 Audio device
Network controller: Broadcom Corporation BCM4328 802.11a/b/g/n
RAID bus controller: Intel 82801 SATA RAID Controller

For the installation, I used these settings:

iATKOS v5i Main System
PC EFI V9
AppleDecrypt
(added SMBIOS-EFI)
9.5.0 Kernel Voodoo
Stock ACPI Modified
Disabler.Kext
ATI
SATA/IDE > Intel SATA
NTFS-3G

If any other information is required to determine what the problem could be, just let me know and I'll look at my system again.

I really appreciate any help.
