I found some time to update my basic EISA support for the Indigo-2
patch, so here it is (only works in PIO mode).
Performance is much better that what it was two months ago, and is
stable for my very basic usage (Indigo-2 as a router... yeah right).
Here is a sample boot :

The machine currently runs with a 3c579 (EISA counterpart of the
3c509), and a HP100 10/100VG whose driver is not very happy on the
Indigo-2... Anyway, the 3Com card is perfectly OK and runs with zero
modification to the driver.
I still have to try an ISA card in this beast, but at least I can now
compile with ISA support (which was crashing the machine before...).
Patch is against 2.4.19-rc1 from CVS as of yesterday. I'd really love
to hear from someone about this (that is, if anyone cares at all...).
