mode 19 comes from get_detailed_timing, while 18 comes from
get_std_timing and timings are calculated by calc_mode_timings (which in
turn calls fb_get_mode). Any chance that there is some error in
fb_get_mode?

I don't know the details about mode calculation and I never had any VESA
spec, ask James here...

I might be missing something jumping in the middle of the discussing but 
there is a GTF paper on creating VESA modes including from stratch 
without edid. The modes generated are pretty close to the standard VESA 
modes. 

The problem is that mode calculated by fb_get_mode is different from the
one that comes from get_detailed_timing.

Also, modes  from fb_get_mode  are different from  XFree modes  so every
time I switch from console to X I have to re-center the screen.

This happens only when modedb is created from edid, not when using the
standard modedb.

Currently create_modedb is unused (the new radeon driver is the first
user of edid stuff) so we may be hitting a real bug.
