I have the same hardware but with 512MB. I have the same problem. The problem occured with alpha 4, alpha 5, and beta 1. After alpha 5 I did a complete reinstall of 7.10, which works perfectly, and then did a new install of beta 1 using update-manager -d.
It still locks up hard after 5 to 10 minutes. I'm usually in Firefox when it locks up but I have had it lock up in other applications including synaptic and xemacs. Last time it locked up was this afternoon after doing a complete apt-get update/apt-get dist-upgrade, so the software was at the latest patch level as of this afternoon (US central standard time).
