HD4250: catalyst 12.6beta not compatible with Ubuntu 12.04's kernel 3.

[psm360]

My specs are:
AMD phenom II 955
MOBO: ASUS M5A88-M
GPU: ATi HD 4250 with catalyst 12.6 beta (latest for HD 4000 series)
I installed ubuntu 12.04 LTS 32bit.
Problem is that Ubuntu 12.04 has kernel 3.2.0 which is not supported by Ati Catalyst 12.6 beta. Currently I am running fglrx graphics drivers downloaded from Ubuntu, but they dont seem to work as UI is very sluggish, even video playback is sluggish.
Now resolution I am thinking is to wait for next catalyst update or to replace ubuntu 12.04 with one with a previous version of kernel which is supported bu catalyst 12.6beta.
Is their any other alternative? please suggest.
