Thinking about downgrading

I have the Intel i915. This card has always given me headaches since I started using Ubuntu. One of the main differences right now is that I have a 22" inch monitor plugged in, but even without the monitor X is still slow.

Take a look at firefox. I have 5 tabs open at the moment.

Do you have an nVidia graphics card?  My desktop does and Firefox has
been a little clunky because of it for a while now.

I haven't spent a lot of time investigating, but maybe there's a way
to downgrade the driver rather than the whole system...
