I experienced some similar problems when I first received my Dell Latitude
C810 which has the same card. In my case the card worked fine after
upgrading to the latest BIOS from Dell.

Interestingly, the card has a similar problem in Windows ME in that it's
won't initialize properly on first boot, but if I remove and reinstall the
driver it comes right up.

I think the problem is that the BIOS fails to initialize the PCI bridge
properly, but this is a total guess.

Anyway, my suggestion would be to verify that you have the most current BIOS
for your system, and select any options at all that would indicate a legacy
system. Also, another stupid suggestion is to try ACPI in the kernel, a
friend of mine insist that his card started working after he simply compiled
in ACPI, he thinks the bridge was brought up in standby mode and somehow
ACPI fixed this (I'm skeptical, but it is just a suggestion).

Later,
Tom
