they are great :)

i haven't used mine under the 2.0 kernels (only 2.2) but i believe that they
are still supported just fine.  a couple things to be aware of though:

 * if you're pcmcia slots are cardbus you need a fairly recent (more recent
   then is in slink/stabe i believe) pcmcia-cs package in order to be able
   to use it.  either upgrade to potato/unstable or compile you own (but
   make sure it's a current version).

 * some of the realports are cardbus cards and some are just pcmcia cards.
   my pcmcia one works great, but my friends cardbus one doesn't.  he "used
   the source" to get his working but i don't know if they are officially 
   supported yet or not.  if yours is a cardbus make sure you have the most
   recent version and check the supported cards list.

you can find out which tty your modem is on by:

heyzeus(larry)$ cat /var/run/stab 
Socket 0: empty
Socket 1: Xircom CEM56 Ethernet/Modem
1       network xirc2ps_cs      0       eth0
1       serial  serial_cs       0       ttyS3   4       67

> Curious.  Perhaps I should be using /dev/ttyS3????

i would think so.  remember that you can exclude certain irq's from being
assinged by the pcmcia drivers by putting lines into /etc/pcmcia/config.opts
like this:

exclude irq 4

hope that helps,
