Downgraded ATI drivers but cannot find Kernel version

Question

After a recent upgrade to kernel 2.6.39 and ATI catalyst 1.6 drivers, I am getting worse performance.
I have downgraded catalyst-utils to 11.4 but cannot downgrade the catalyst driver to 11.4 as it requires a
kernel <2.6.39
[root@orac boot]# pacman -U /var/cache/pacman/pkg/catalyst-11.4-1-i686.pkg.tar.xz
warning: downgrading package catalyst (11.6-1 => 11.4-1)
resolving dependencies...
warning: cannot resolve "kernel26<2.6.39", a dependency of "catalyst"
:: The following package cannot be upgraded due to unresolvable dependencies:
      catalyst
Do you want to skip the above package for this upgrade? [y/N]
error: failed to prepare transaction (could not satisfy dependencies)
:: catalyst: requires kernel26<2.6.39
My problem is I dont know how to find the Arch 2-6.38.4 kernel (or previous version).
The kernel name always appears as kernel26, so how do I find a particular version?
I have the old 2.6.38 modules in /lib/modules
[root@orac pkg]# ls /lib/modules/
2.6.38-ARCH  2.6.39-ARCH  fglrx  fglrxold
but do not have 2.6.38-ARCH in /var/cache/pacman/pkg
Thanks in advance

Answer 1

I use Catalyst 11.4 with kernel 2.6.39, but instead of catalyst I use catalyst-hook to build the fglrx module after kernel updates and it works perfectly.
$ uname -sr
Linux 2.6.39-ARCH
$ pacman -Qs catalyst
local/catalyst-hook 11.4-1 [3.15 MB]
AMD/ATI drivers. Auto re-compile the fglrx module when kernel update
(mkinitcpio's hook)
local/catalyst-utils 11.4-1 [70.30 MB]
AMD/ATI Catalyst drivers utilities and libraries.
