that thread is different and actually the change I mentioned there came
in around 2.6.9 and was for serial_cs only.

So this is a CardBus card and not a PCMCIA card. These cards are very
rare and I don't have one of these. The Socket card is still an old ISA
PCMCIA card.

It can also work in H4 mode and then you need to use "csr" or your baud
rate is wrong. The hciattach tool gives you a lot of parameters and you
should try some of them.

Since Fabrizio works for Philips, you might wanna contact him and don't
forget to put me on CC. It seems that the current kernel is still
missing some patches. And btw feel free to donate one of these cards to
me for testing.
