SubjectRe: IDE pnp interface on a SB16 not working

Umm, well, now I'm not so sure about this, I got the card to work under
kernel 2.2.20, it seems to be a problem with 2.4.X. I was gonna test under
2.2 setting the parameters by hand on lilo and adding noprobes using then
isapnptools and then loading the cd driver module, this had resulted ok to
me with other card in non PNP BIOS. It resulted that this was not necesary
as the BIOS was setting up the IDE PNP interface.

So... setting all the IDE stuff on the kernel, not as modules, on 2.2 (no
PNP support at all) worked ok, while setting up a similar 2.4 kernel failed.

I'm including now output from 2.4 kernels and 2.2.20 one in case this puts
any light on this issue:

Well, guess this is all I can offer right now, if you need any tests done,
don't hesitate to contact me.
