don't know if this can help you, but when I made the patch mentioned
above (to get my Socket CF bluetooth card working - it worked under 2.4
but not 2.6, like yours) I compared the serial_cs modules in both kernel
versions and found that in 2.6, some code is missing which was present
in 2.4, especially everything regarding high-speed UART chips. Don't know
why all this was removed though...
Because of the missing init code the UART chip didn't get initialized
with the baud rate which hciattach supplied to the serial driver.

Regards

Mathias
