at the moment some serial based PCMCIA or CF Bluetooth cards work and
some don't. I have no clue why this is so and I am no expert when it
comes to UART specific stuff. Some of these cards indeed work with a 2.4
kernel.

Actually I think I have most of them at home. However there are a lot
more out there and it seems that any new PCMCIA of CF Bluetooth card is
a serial card with a Bluetooth chip attached to its UART.

I will do and I can also add them to my -mh patches.
