Yes. That looks very much like my problem. It is a bit of a show stopper
on netbooks.

Any chance of debian applying one of the suggested patches, or is there
likely to be fairly quick action on the main release?

Otherwise, I guess I could try and patch and compile myself, although I
don't fancy that on a netbook...

Thanks for the helpful reply.
