Hello,

The .27 angstrom kernels have all the patches Måns wrote, so why not
use that?

Okay, no problem. Do I have to update my openembedded-repo or where
can I download a precompiled one?

I used the one from
http://dominion.thruhere.net/koen/OE/omapfb-overlay/ With 800x600@60
as a command line parameter I get:
root@beagleboard:~# fbset
mode "800x600-49"
        # D: 28.800 MHz, H: 30.000 kHz, V: 48.544 Hz
        geometry 800 600 800 600 16
        timings 34722 48 80 3 11 32 4
        accel false
        rgba 5/11,6/5,5/0,0/0
endmode

which my monitor does not support. Do I miss something?

I guess the kernel can't find a divisor than will do 60Hz and does
49Hz as 'best effort'

I just send a very very tiny patch to mans to get truly 60Hz (new
pixel clock value).

I believe it is best to post patches here and cross-post to linux-omap, rather than e-mailing patches to an individual who may or may not have time to examine.
