OK, this is a beginnning :)

I also had to replace all (mis)usages of __FUNCTION__ in printks,
  ERROR and WARNING macros to get the driver to build, and finally
  I built and loaded it.

So - with this driver the IrDA communication hangs as soon as the
  first messages try to go from the PPP script to the phone, and I
  have to kill irattach and restart it to see anything more from
  irdadump.

Relevant info... from dmesg:

(1152000 should possibly be 115200 ?)


And irdadump says:

Then hangs (all this is with the 20021007 driver).


Hope it's helpful, ciao,
