How can I use 'newer' version of Intel X drivers?

[Chris G]

I have a problem with my 9.04 [x]ubuntu system and the Intel graphics
drivers.  It seems to be pretty exactly the problem desribed at:-

    https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/375545

Since a new version of the Intel drivers seems to fix the problem
(9.04 provides 2.6.3, fix is in 2.7.1) it would seem that if I install
the later drivers it should solve my problem.

Can anyone tell me how I go about getting the newer Intel display
drivers please.
