Hang at Executing all Device _STA and_INI methods

Hi,
Given recent changes in APIC code on some systems in 2.5.74, I decided to see whether it makes any difference, but the kernel hangs at boot.

My system is: ASUS L3800C notebook, P4-M (no HT), i845M chipset. I wasn't really sure whether the system had any APIC whatsoever, because every time I tried to compile in APIC support, it backed out with No local APIC found.
Note: ACPI without APIC works fine.

I compiled 2.5.74 with:
CONFIG_X86_UP_APIC=y
CONFIG_X86_UP_IOAPIC=y
CONFIG_X86_LOCAL_APIC=y
CONFIG_X86_IO_APIC=y

The system booted well, until Executing all Device _STA and_INI methods appeared, and it seemed to hang in the middle of doing that (SysRq not responding).

Running the same kernel with acpi=off works fine whatsoever and produces the following lines:
Local APIC disabled by BIOS -- reenabling.
Found and enabled local APIC!
[...]
enabled ExtINT on CPU#0
ESR value before enabling vector: 00000000
ESR value after enabling vector: 00000000
Using local APIC timer interrupts.
calibrating APIC timer ...
..... CPU clock speed is 1699.0776 MHz.
..... host bus clock speed is 99.0986 MHz.

It's not that I need APIC anyway, but I figured it may be worth reporting. Best regards,
