thanks a lot. it works for me, with the values {1280, 720, 54, 28, 0} for a 720p HDTV
in order to ajust to me right values I have need to recompile several times the kernel but it's simple and quick just folowing this steps. I asume that your use the first guide to create your own kernel and you are not happy with the result.
open a terminal
goto where you have the linux folder with
cd linux
delete only the presious complied ps3fb
rm /drivers/video/ps3fb.o
modify the source file with your new values for test
gedit /drivers/video/ps3fb.c
recompile the kernel (you will see this is very faster now)
make vmlinux
copy the new kernel to the boot folder
cp vmlinux /boot/vmlinux_NTFS_UDF
overwrite it with y
cp also the System.map (not sure if needed, but is only a file and I did it)
cp System.map /boot/System.map
overwrite it with y
reboot and check the new results, if you are not happy test again with new values ;-)
