Hi,
I have trouble getting b43 to work with my card. The trouble 
seems to be with the transmit/receive power, but I have no 
idea what to try next.

The card is:
lspci -vvnn -s 01:06.0
01:06.0 Network controller [0280]: Broadcom Corporation BCM4318 [AirForce One 54g] 802.11g Wireless LAN 
Controller [14e4:4318] (rev 02)
	Subsystem: ASUSTeK Computer Inc. Unknown device [1043:100f]
	Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B-
	Status: Cap- 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR-
	Latency: 32
	Interrupt: pin A routed to IRQ 16
	Region 0: Memory at fdffe000 (32-bit, non-prefetchable) [size=8K]

When I use the old driver, in dmesg I get:

Any ideas?
