I tried this and got it to work. Thanks for the hint!
The Inspiron 7500 has one serial port, which I configured as COM1
(irq=4, io=0x3f8) in the BIOS setup. The IR is configured as SIR and
COM2 (irq=3, io=0x2f8). Both are recognized by the kernel as ttyS0 and
ttyS1.
IRDA is activated by the following command sequence:
setserial /dev/ttyS1 port 0 irq 0 uart none
modprobe irport io=0x2f8 irq=3
irattach irda0 -s 1
After that I can successfully synchronize my palm via /dev/ircomm0.
But I noticed, that the speed via IR is at least twice slower than via a
serial cable, allthough both are operating at 115.200. The reason for
this may be the battery, which was very low (2.25V) during the test. The
distance between palm and laptop was about 20cm.

Mine is an un-patched 2.2.19 kernel, the same with a 2.2.14 kernel from
Suse (heavily patched) didn't work.

It really did. Thanks a lot.
