No. What I'd do is make sure all the -devel stuff is installed, and
build your own kernel. I long ago, committed most of that detail
work to a couple of scripts that get edited regularly to keep the
version numbers compliant to what I'm building. One grabs the old
.config and makeit files from the previous version, hides it, unpacks
the newer one, applies any patches, restores the .config & makeit
files, runs a make oldconfig which incorporates all your special
options into the new .config, and asks you questions about any
changed/new options.
Then I run a make xconfig to double check, edit the copy of makit
(my 2nd script) to fix the version to match the Makefiles version &
then run that script which does the compile and install stuff.
A couple of sips of coffee later I can edit grub.conf (may be
menu.lst on some distros) to add the new kernel and initrd & reboot.
20 minutes if I get distracted, 2.8G athlon XP here.
Then you know you have a kernel that matches your hardware.
And currently running 2.6.14-rc2, uptime 7d 15:42.
And I'm not exactly a youngster, I'll be 71 next week.
