Ok, found it.

It really looks like the new EISA probing code in hp100 never got
tested, since a precious offset has disappeared during the rewriting
process.

Please note that you still need to enable the device by hand, since
your BIOS (or maybe the EISA CFG file, since I'm seeing the exact same
problem on a Compaq machine here) doesn't properly enable the card.

Here is what I'm getting on my test system :

EISA: Probing bus 0 at 0000:00:0f.0
EISA: Mainboard CPQ0541 detected.
EISA: slot 1 : DEC4250 detected.
EISA: slot 2 : UNB0048 detected.
EISA: slot 3 : HWP1940 detected (forced enabled).
hp100: Using (slow) programmed i/o mode.
hp100: at 0x3c38, IRQ 3, EISA bus, 128k SRAM (rx/tx 75%).
hp100: Adapter is attached to 10Mb/s network (10baseT).
EISA: slot 4 : NVL0701 detected.
