OK - 2M is not much.
That an ISA ET4000 always worked for me is not much of help, I think.
Maybe a G450 or S3 will work, but can't say for shure.
I would say try out what you have and if you have to buy a card then
try getting a used Millenium with 4 or 8M.

But who wants this if one can run FreeBSD :)
The PC164 is very well supported, the only drawback is the interrupt
PAL, which has problems masking interrupts, therefor we currently
raise the CPU IPL as a workaround.
As a result you'll see additional interrupt latency on higher interrupt
load.
Unfortunately both of my PC164 are production machines and I can't
analyse the PAL.
