[Gta04-owner] wlan problem

Hello all,

For the last few weeks, wlan has not worked on my GTA04.  I've tried 
various images including the hw-validation image and it doesn't seem to 
see anything at mmc1.  Tonight  I installed the newest u-boot image with 
the extra wlan tests and clipped some leads from the debug connector to 
my old laptop so I could use the serial port.

Here is the result of systest wlan:

GTA04 # systest wlan
activate WiFi/BT reset
power on VAUX4
release WiFi/BT reset
UART1 RTS: 1
UART1 CTS: 1
UART1 TX:  1
UART1 RX:  1
UART2 RTS: 1
UART2 CTS: 0
UART2 TX:  1
UART2 RX:  1
HCI send: 01 02 04
HCI receive: 00
clock 1 --> feedback 0
clock 1 --> feedback 0
clock 1 --> feedback 0
clock 1 --> feedback 0

and here is the result of hw-test on the hw-validation image:

Are there any things I should try?  Is it strange that bluetooth seems 
to be working?  I haven't tested it beyond hw-validation tests.

Thanks,
Ben
