[ltp] 600E: serial + IR + sound + PC-modem = IRQ shortage

I'm trying to set up a 600E (RedHat 6.2, kernel 2.2.14-5.0, PCMCIA utils
3.1.14) with the following active:
Serial A (for DTE connection as a serial console)
Infrared (for Pilot infrared sync)
Parallel (for printing)
10/100Mb 3Com 3CCFE575B/3CXFE575B Fast EtherLink XL (work Ethernet)
3Com/Megahertz 3CXEM556 Ethernet/Modem (modem use only)
Alsa sound (for fun)
Right now, I've got most of the pieces working. The serial port (/dev/ttyS0) is
enabled and works. Printing works. The 10/100Mb ethernet PCMCIA card works.
Sound works.
The internal modem is disabled (via the Thinkpad utilites under Windows).
I'm having trouble with the Infrared port (an issue, but not critical), and the
PCMCIA modem (much more important).
When I insert the PCMCIA combo card, I get the "high/low" tones, and the
following errors are logged:
kernel: 3c589_cs: RequestIRQ: Resource in use
cardmgr[428]: get dev info on socket 1 failed: Resource temporarily una
vailable
I know that the card works (it was fine until I enabled the IR port). I
haven't found a way to force it to use another IRQ.
Does anyone have any suggestions?
