I had this trouble with my Motorola Lifestyle 28.8 Internal:  it thinks
it's Plug and Play, but it's not REALLY Plug and Play, or maybe my BIOS
isn't really PnP, or something, but it doesn't exist at first bootup.  I
had to kick the old DOS PnP drivers in to load right before Linux boots to
assign it an address, and then used the line:

setserial /dev/cua3 port 0x2E0 irq 5 autoconfig

in /etc/rc.d/rc.serial, and that detected it just fine.  Then I linked
/dev/modem over to /dev/cua3, and presto :)  It didn't work for me without
the 'autoconfig' for some reason, so i tossed that in and poof.  :)

Which /dev/cua you use doesn't seem to matter, since W*n95 thinks my modem
is on "com5" (dumb OS), but it reports it at those port and IRQ settings,
so things should work OK.

don't forget to insert a call to rc.serial in the appropriate rc.file
(rc.S, i think?  I don't remember) if something isn't already calling it at
startup, or you'll wonder why nothing seems to have changed :)
