Geode GX/SC120x framebuffer support on a 2.6 kernel

[Massimo De Beni <maxdb82 gmail com>]

Hi, sorry if I'm bothering you...

I'm working to upgrade the kernel of a Set Top Box to the latest 2.6.14 from a 2.4.12;
The processor is a Geode(TM) Integrated Processor by National Semi with ~267 cpu MHz.
I menaged to get a linux kernel image that works well exept for the
most important thing in a STB: in fact the video goes black after the
boot sequence. I didn't undestand what shall I do to make framebuffer
support work with an NSC Geode GX/SC120x chipset: shall I use vesafb,
or I have to use a different kernel framebuffer module? In kernel
2.4.12 there was a module called 'geodefb' which could be loaded with
boot parameters like these: << video=geodefb:vmode:PAL-720x576-16 >>
While in standard kernels 2.6.x there isn't such a module: could it be
that it's no more available a linux kernel 2.6 frame buffer driver for
Geode SC120x ???

I'm lost: I've tried ALL the patch that I've found in Google but nothing seems to work: if anyone have a suggestion I would really appreciate!

Thanks all in advance
