Mason, to my knowledge the kt266 should support the Athlon XP that use a 266MHz FSB. Heck, even some kt133a support Athlon XP's as the kt133a does also have an effective 266MHz bus.

With my nForce2 board, the APIC doesn't quite work. It works fine with WinXP. I see 2x+ IRQs. With the stock 2.4.21-pre6 kernel, IO-APIC doesn't even get detected. Using the latest 2.4.21-pre6 ACPI patch, I am able to get IO-APIC, however, for IRQs higher than 15, the PCI IRQ routing simply doesn't work. Someone has posted to the acpi-devel list, but there hasn't been a response to it yet. With some of ACPI's core developers working for Intel, I doubt this is high on their priority to fix PCI IRQ routing on a chipset designed for its rival AMD.

gambit:~> cat /proc/mtrr
reg00: base=0x00000000 ( 0MB), size= 512MB: write-back, count=1
reg01: base=0xd0000000 (3328MB), size= 128MB: write-combining, count=1
reg02: base=0xd8000000 (3456MB), size= 64MB: write-combining, count=1

MTRR is detected and looks to work.

The GIMP loads up, but I haven't had it open anything large.

I've not tried watching DVDs on Linux on the nForce2 system. I doubt that it will work since I can't even play MPEGs. It looks like without agpgart, XVideo extension doesn't work properly.
