Greetings,
I tried this setup this weekend:
   Mac II with RasterOps 264 board

Seems to work fine except that I get the following error
before the screen clear happens:
   Error -37 trying to open slot 0xd video driver
   Error -37 processing video card slot 0xd sRsrcID 0x90
   Warning - error -37 turning off interrupts - booting anyway

I assume it's complaining because it's a 24 bit card (it is
in one bit mode when I boot).

But it basically works, so I'm not complaining.

Then I install an old Asante MacCon MC3NB ethernet card
(enet chip is DP83902). It recognizes the card and I can ifconfig
it, but it totally hangs when I try to send any traffic out the
port (ping, etc). A break (over serial console) into ddb and 
a trace gives me:

I remember hearing about problems between certain ethernet
cards and 24 bit video cards. I don't have an 8 bit card and
I (unfortunately) can't boot without the video card. (Does
anyone know if a Mac _can_ be booted w/o a video card?)

So, has anyone played with a similar setup recently? Is the
video card at fault, meaning I should but get an 8 bit card,
or is it just the horrible interrupt conflict monster rearing
it's ugly head again?

Thanks.

P.S. I've also got a Cabletron ethernet card here that uses
a DP8390 chip, but it's not even recognized at boot time as
an ethernet card. How does the kernel decide which cards are
which devices? Can I just add the "name" of the card somewhere 
in the kernel for it to be recognized?
