MP 780 - audio, Irda and USB on PCMCIA

Hi all!

  It's my first mail to this community
  I have a NEC Mobile Pro 780 with NetBSD 3.1 on board. It's running
and works pretty good, but maybe can be better? I'm looking for short
answer about running audio on it (probably:
vraiu0 at vr4102ip0 addr 0x0b000160-017f
audio0 at vraiu0: half duplex
entries in kernel configuration should be enough - can anybody
correct, if not?) and IrDA. I can't find any tip, how to use it. It's
possible at all? Or maybe bluetooth trough usb on pcmcia card? I have
no idea if it can works.

I hope my english will be understandable for you

Best regards

Mariusz
