Yes there were interrupts reported (I thought it was obviuos, since
the card worked with most low load operations). It pinged, i could telnet
into it, i could open a gnome-terminal on it with X output to a remote X
server...

2.2.xx sure.

I don't have info handy (it's running on the GA-71XE, right now)
but I'm pretty sure the card was not sharing IRQs. The K7V manual has
info on which PCI slots share INTs, and I put the card into the 2nd
PCI slot, which is marked INT-B 'not shared'.

win2k is not one issue of mine. B-)
The K7V has a default setting of PCI latency timer of `32' (whatever
it means exactly) and the card driver reported to raise it to `64'.
I set that value on the BIOS settings, and the card seemed fine
with it. But it timed out on transmission the same way.
The GA-71XE has a default value of `64', BTW.

I think so... there is no info on which slots are bus-master or not.
I think they are all capable of receiving bus-mastering cards.

I suspect some PCI issues. After all, both the P5A and the K7V are from
the same manufacturer. I'll try to get another brand soon.
