hi all,

I have a strange problem with net4501 + Mikrotik, it does not see D-Link
DWL-AG520 (AR51212) in the PCI slot. Older version of Soekris board
(with 83815) works ok. In both cases, the card is correctly seen during
boot (ShowPCI), but Mikrotik's show pci command displays irq 0 and no
wlan interface.
What's more strange, when I put some other card in the mini-pci slot, it
starts to work correctly. It doesn't matter what the mini-pci card is,
the OS doesn't even have to have a driver for it.

DWL-AG520 is 5V, I use 5V power supply and JP9 jumper. Other PCI cards
(PRISM based) seem to work, (I tried 5V and 3.3V versions). I'm pretty
sure I had the same problem with DWL-AB510 too, not certain though.

In the two cases below, the only difference was Soekris board (old
version vs new version). Notice irq 0 in the latter case.
