Look for something using the IRQ configured for the /dev/ttySx or /dev/cua0
that your modem uses. One way is "cat /proc/interrupts" which will show
the active IRQs. It's conceivable that a new kernel might configure a
device with a different IRQ than the old kernel did.
Have you linux/Documentation/Changes file in the Linux source tree? I
don't think this pertains to the changes in networking there but you should
be aware that there are some.
Note to Julius: The files copied to the kernel source tree for a 2.2.10
kernel are not likely to be significant. For 2.2.9 there were three files
copied and none were used in the kernel compile. The 2.2.8+ kernel PPP
support code is newer than ppp-2.3.7 and perhaps later versions of pppd.
