That error usually indicates an IRQ conflict. Turn off Plug-N-Play OS support in your BIOS, as it can interfere with the initialization of some PCI cards under Linux. Also, check my post in this thread
for a few more suggestions. Sorry, I know it's not the "tons of detail" you asked for, but I should have been asleep hours ago, and detail just isn't in the brain right now.
If you know the card is working, the PNP OS switch should be the key, though.
