Here is the boot log from booting my EPoX MF570SLI in nolapic mode.
When I boot without nolapic or noapic I get as far as

io scheduler cfq registered (default)

I can't boot to serial right now.

You are getting this as the next line after that:

0000:00:02.1 EHCI: BIOS handoff failed (BIOS bug ?) 01010001

You might want to try upgrading your BIOS, it seems like the BIOS is not 
letting go of the USB controller when Linux tries to take over. I don't 
know if that's related to the problem though.

If that doesn't work, I'd try a newer kernel version.

I completely disabled USB in the BIOS. I get a bit further, but still,
a hang. See my other msgs.

I recently tried a bunch of stuff:

Things that do not help:
1. adding nolapic_timer
2. adding either of acpi_skip_timer, acpi_use_time_override
3. with or without nolapic, adding acpi_serialize hangs the boot.

Additional debugging:
1. adding apic=debug
2. earlyprintk=vga

One time, I got far enough to see:

Booting
Initializing CPU #1
Stuck ??
Inquiring remote #1 ...
... APIC #1 ID: 01000000
... APIC #1 VERSION: 80050010
... APIC #1 SPIN: 000001ff
Brought up 1 CPUs
<hang here>

Then I tried 2.6.25.5 (which I can boot from but cannot use as yet)...
and it boots without nolapic or noapic.
Below, please find the dmesg for that. I added "apic=debug earlyprintk=vga".
