PBG3Series and pre-R5: a little bit further

Hello *,

Batmensch : to be continued on the list

This afternoon I discovered the XF86Config.controlfb of Mr T. Oe I believe.
I tried it on my 8600, thinking it would accelerate somethings...(may be
later with the controlfb.c took at the same archive) but instead I took
some time to better use the "Monitor" statement of the XF86Config.
I set the good values for my monitor (Hitachi CM751ET) and now XFBDev
behaves slightly better to my taste.
For example I now get rid of the strange 1280x1024 real over 1280x16XX
virtual resolution of the very generic XF86Config.pmac.

Wich leaded me to this : what about if XFBDev tryied the same weird
resolutions on the poor LCD of my PBG3 ? (I use XF86Config.pmac on the
PBG3). Since the beginning I though it would be an error in the
resolution , this strange behavior of two small X screens in two
quarters etc..

I tried to include in my 8600's XF86Config the LCD settings, but I lack
some info (how to set 1024x768 at 60Hz)
Well, I hooked up the hitachi on the PBG3, with the SAME config as the
8600 (works here in 1280x1024 at 75Hz) and it didn't work.
I got basically the same error than here (no valid modes found, after
having eliminated all modes), using my half definition for the PBG3 14,1
LCD :

Here is my long-awaited ;-) XF86Config :

My question is : is it necessary to tune things to this end to get this
[snip] of XFBdev working ?
Has it already be done ? If yes where ?
