SubjectPATCH: toshoboe 2.4 PCI api
Hi,

I cleaned up the Toshoboe IrDA driver:
- Ported to Linux 2.4 PCI API. Including PowerManagement this time.
- got rid of static dev array, using pci device data
- some misc cleanups.

Tested that IrDA still works on Toshiba Satellite 4080XCDT with irdadump
and a Siemens S25.

Ciao, Marcus
