No. I'd take 2.6.11 and, yes, apply 2.6.12-rc4 against it:
http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.11.tar.bz2
And I'd recommend the patch against the latest "kernel ELF core dump
privilege elevation". You can get it here:
wget <ftp://ftp.kernel.org/pub/linux/kernel/people/colin/patches/2.6.12-rc4/can-2005-1263.patch>
I applied the latter after applying 2.6.12-rc4. IIRC.
If you want to try it:
My config:
<http://www.geocities.com/wolfgangpfeiffer/config-2.6.12-rc4-selinux1.txt>
With this config you don't need an initrd ... :)
And selinux is disabled at boot.
And I enabled a blinking LED for hard disk activity (actually the most
important setting at all: In the end, what is a computer if it doesn't
blink :::)))
But as I said: I have problems with ALSA (no sound so far) and with
pbbuttonsd: I enabled userspace Power Management in the .config, and
I'm not sure yet why the speed on the machine (Titanium IV, 867 MHz)
is set to ~665 MHz after booting the machine.
I could correct the speed with this helper, IIRC:
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq > /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed
So please have a look to
Processor ---> Default CPUFreq governor (userspace)
and to the sound settings in this .config
But USB mouse, firewire, keyboard, i.e. the most important stuff,
worked out of the box with this .config ...

package:

Good luck!
