Unexpected IO-APIC

This is on a uniprocessor machine, but it sounded like a good idea to
enable io-apic, since the BIOS has APIC set instead of PIC. Nvidia
video driver warns againtst it, but I thought I'd blow smoke into that
warning's face.

I feel like such a newb, it sez to report this to you, so I thought I'd
do that. This is with 2.4.22pre6...

BTW, I'm getting better at compiling the kernel. I think I'm down to
~5~ times a day and I've only got a few unresolved dependencies
remaining...

If you're interested, in more info, please let me know, I'll be glad to
email /var/log/messages or whatever you'd like.

One question though, if it has any relevance to anything in particular,
I dunno...

This a P4 2.4ghz 533mhz fsb shmengie. It's dual bootable in both W2k
and Linux. I run setiathome on both, because I can, but the Linux
version is consistently slower that the NT version. This confounds me.
I had hoped/expected the Linux version to be faster than the NT
version. The Linux version is an i686 compiled/linked according to
their website. As far as I know the NT version is i386. I've got this
system overclocked to maximum stable as you can see here. If you have
any insight, I'd appreciate it . If not, no sweat.
