Well, yes and no.
I've got an 8810 and I've been trying to get it to work with
Linux/IrDA for a year or so, all with varying results, both because
of changes in Linux/IrDA and changes in the Nokia firmware.

Yes. Read on..

Nokia is messing with their IrDA-stack, obviously. In one revision of the
software it works 100% with Linux/IrDA, in another it doesn't work at all.
I've also tried making a PalmIII talk to the 8810 (summer 99, older firmware
which worked fine with Linux/IrDA) but that failed completely. I heard
somewhere that the Palms are quite picky about who/what they play with and I
suspect Nokia didn't do their thing entirely right back then. Haven't tried
again lately, either.
Anyway, the last two revisions of firmware I've had have worked pretty nicely
with Linux/IrDA. Recently (2.2.14irda1 I believe) some of the IrCOMM stuff in
Linux/IrDA changed, I've upgraded to 2.2.15pre3 to test the smc-ircc driver
(which works superbly if I hardcode io[]- and io2[]-values into it..
I got a call to the "modem"-number of my subscription, making the phone cry
out "Data call" and asking me to enable Ir communication..
I had all modules loaded (irda, irport, smc-ircc, ircomm, ircomm-tty) and
minicom set to use /dev/ircomm0. Fired up minicom (phone not discovered),
typed "at<CR>" hoping for Linux to start discovering, waited a couple of secs,
remembered that the phone didn't have Ir communication enabled, enabled it on
the phone and voila, "at<CR>OK<CR>" showed up along with the RING:s.. :)
Unfortunately, I didn't get a CONNECT after my ata<CR>, only the CARRIER,
since whoever was at the other end probably called the wrong number, but still
everything survived a couple of difficult tests.
