I installed sled11 x86_64 on my dell latitude d630 using both the A04 and A15
BIOS. With the A04 BIOS the card is recognized and three ttyUSB# devices are
created. When I update the system BIOS to A15 the card is not recognized and I
get the following error in /var/log/messages.

Something has changed in the newer BIOS that caused openSUSE 11, 11.1 SLED 11
to not recognize the AC875 card. The card works fine under SLED 10 SP2 with
both BIOS versions.
