Most applications will work just fine when you upgrade the kernel from
2.2.x to 2.4.x.  The only exceptions are applications that directly
manipulate kernel data structures or directly access the hardware, like
the Thinkpad Control utilities (tpctl and ntpctl).  Those applications
will ahve to be recompiled against the 2.4.x kernel headers, which is
slightly annoying, but really no big deal.  Things like Netscape, xterm,
X-servers, all the KDE and GNOME things I've tried, and even Oracle
won't even notice the difference between 2.2 and 2.4.

There's a problem with cdrecord and 2.4.x, which can be easily
fixed by adding the following line to /etc/fstab:

none            /var/shm                  shm       exec,dev,suid,rw 0 0

(You must "mkdir /var/shm" if that mount point doesn't exist already.)

I haven't seen any other incompatibilities.
