So, after some nice dialogs with Hartin Husemann and some valuable hints from
him, and some experimenting by me, the problem is finally solved. As this seems
to be a more generic PCI problem, which can happen with differend cards also, i
want to post the very simple solution here, so the next one has more success
when google'ing for "can't map card".

The problem seems to be the PCI bus/bridge drivers not configuring the cards in
some cases (should they?). So the cards don't have any IRQs assigned, don't
want to map I/O or Memory and some other strange effects in pcictl-dumps.

The strange thing: Some cards (like the fxp0 EtherExpress card) are configured
correctly, and others (like Fritz!PCI, 3C905, Altera Flex thing, and even
onboard USB) aren't configured.

The solution: Check your BIOS settings and set "PnP aware OS" to "No".

So found on a newer ASUS board, but this might happen on other boards also.
Chipset: some VIA KT400 or so.

...Michael
