Does anyone know if IRDA (for networking) is still supported by Linux?

I need to build a gateway from IrDA to ethernet to make legacy palmos devices talk to the internet.

I vaguely remember IrDA having different protocols, and palmOS not supporting all of them. Maybe they did serial to ppp, like a dial-up modem? 

And there were devices that were palm compatible, like this one...

Sadly these are long gone and not available even used. 

So, I don't know where to start. Would Fedora Linux and the cheap USB-IrDA adapters work? 

If this list is not the right place, is there a forum with palmOS savvy people where I should ask? Thanks in advance for any pointers...
