Not much of interest - they all either use the i810 or Intel driver; no HorizSync or VertRefresh specified. Seems the default is good enough ...
The problems I had with Intrepid were with the install - needed to come up in a degraded video mode.
Check you have the "latest" BIOS level -A32.
is another thread you might want to look at.
Ignore the zenwalk comment - re-install went o.k. Occasionally have to kick X into action with <alt>-<ctrl>-<bksp> when it stalls on a blank screen on startup.
