Which applications do require a 2.4 kernel?

You could test following:

Edit /etc/rc.sysinit and add at it's end, right before the last lines
for exit signals to rhgb, code like this:

rm -f /dev/mouse
if [ $(uname -r | cut -b -3) == "2.4" ]; then
    ln -sf /dev/psaux /dev/mouse
else
    ln -sf /dev/input/mice /dev/mouse
fi

Use in /etc/X11/xorg.conf as mouse device location /dev/mouse.
If you run service gpm you'll have to care for that too. Copy
/etc/sysconfig/gpm (with current settings for kernel 2.6) to
/etc/sysconfig/gpm-2.6. Copy it to to /etc/sysconfig/gpm-2.4 and change
the DEVICE line to DEVICE="/dev/mouse". At top of /etc/init.d/gpm you'll
have to change the sourcing of the gpm sysconfig file.

[ -e /etc/sysconfig/gpm ] && . /etc/sysconfig/gpm

becomes

rm -f /etc/sysconfig/gpm
if [ $(uname -r | cut -b -3) == "2.4" ]; then
    [ -e /etc/sysconfig/gpm-2.4 ] && cp -a /etc/sysconfig/gpm-2.4
/etc/sysconfig/gpm
else [ -e /etc/sysconfig/gpm-2.6 ] && cp -a /etc/sysconfig/gpm-2.6
/etc/sysconfig/gpm
fi
[ -e /etc/sysconfig/gpm ] && . /etc/sysconfig/gpm

Do the same with the /etc/sysconfig/mouse config file according line
DEVICE=... This sysconfig file is source right below the gpm sysconfig
file in the gpm init script.

This all is untested and *might* work! I give not any warranty! Keep
care for mistypings.
