I have the same problem on HP nx6110 with the same graphics card. Debian testting.
I spent lot of time to get it worgking and now I am using old version 2:1.7.2-4 with vbetool, without 3d rendering. With 3d rendering it makes this problem and with newer version, it doesn't do anything, only black screen, even if 3d rendering is off :-(
