[Linux-fbdev-users] Framebuffer with TV-Out @ PAL

[Georg P. B. <geo...@st...>]

Hi!

I don't know if this list is the correct one, feel free to correct me...

I have a Voodoo3 running with TV out on a PAL TV (no other monitor
available...)
Since this TV only can use PAL@50Hz but all framebuffer modelines (fbset
and the kernels modedb) only support 60Hz I've written my own modelines
for use with it (added below).
I'd appreciate it greatly if somebody could test if they work for him,
too.
It would also be nice if I knew where to submit patches, didn't find
this info on the 'net...

Thanks
  Georg Philipp Burth
