This won't work well without AX.25 also being in the kernel. BUT it is 
much much better to use KISS as a module (CONFIG_MKISS=m) instead.

mv .config .config.old
sed 's/CONFIG_MKISS=y/CONFIG_MKISS=m/' <.config.old >.config
make modules
make modules-install
make bzImage (only needed to rebuild kernel without mkiss in it)
...whatever steps you use to install new kernel 
...and update MBR (i.e. run lilo)

reboot

depmod -a

/sbin/modprobe ax25
/sbin/modprobe mkiss
kissattach ...

I would recommend building a kernel from generic 2.4.19 sources 
(www.us.kernel.org) rather than RedHat's kernel source rpm unless you need to 
use RedHat's patches for some non-standard reason. 2.4.19 has some fixes
for amateur radio.

I hope that helps,
