I think that I found the problem. The minimun clock frequency in line 844
of geode_driver.c is too high to allow the lower resolutions to be accepted:
static ClockRange GeodeClockRange = { NULL, 25175, 135000, 0, FALSE, TRUE,
1, 1, 0 };
Changing the minimum clock frequency to 1 solves the problem:
static ClockRange GeodeClockRange = { NULL, 1, 135000, 0, FALSE, TRUE, 1, 1,
0 };
Clearly, this is not a valid lower boundery, but it solves the problem, and
it looks like other drivers are taking the same approach of setting a
minimum of 0 or 1.
Also, the HorizSync range in XF86Config will need to allow a lower minimum
value so something like 10-60 will be necessary.
Hope this helps others,
Ed
