I think the ACPI issue is a red herring. I didn't realise it was enabled when I built the kernel and was surprised when I found it trying to share an IRQ with the network card. It's not enabled any more, but the card still doesn't work :(

I'm retyping this from the screen, since I can't get onto it over the network. I've checked for errors and don't see any, but you know how it is...
With 2.2.14, I get:
0: XT-PIC timer 1: XT-PIC keyboard 2: XT-PIC cascade 7: XT-PIC soundblaster 9: XT-PIC eth0 10: XT-PIC aic7xxx 11: XT-PIC bttv 12: XT-PIC PS/2 mouse 13: XT-PIC fpu 14: XT-PIC ide0
2.3.33 gives me:
0: XT-PIC timer 1: XT-PIC keyboard 2: XT-PIC cascade 7: XT-PIC soundblaster 9: XT-PIC eth0 10: XT-PIC aic7xxx 11: XT-PIC uhci, bttv 12: XT-PIC PS/2 mouse 13: XT-PIC fpu 14: XT-PIC ide0
As far as I can ascertain, under Win98, I have:
0 timer 1 keyboard 2 interrupt controller 3 COM2 4 COM1 5 Maxtrox G200 and Hollywood Plus MP3 decoder 6 Floppy controller 7 Soundblaster 16 8 Clock 9 3c509 10 AHA2940 11 WinTV and PCI/USB controller 12 Mouse 13 FPU 14 Primary IDE Controller 15 Secondary IDE Controller
I see arp requests from the machine on the network, and I see responses from the remote systems to those requests. Clearly the kernel doesn't see them though, and the IRQ count as displayed in /proc/interrupts never gets above zero.
I'm building 2.3.39 as I type, but I don't hold out a whole lot of hope for anything different. After that I'm going to start pulling boards out until the card starts working again, but I don't think that's going to help me understand the problem much, nor to fix it. If it didn't all work under win98, I'd assume there was a hardware problem of some sort and indeed that could still be the case. I just don't know how to move forward with this now.
