It is possible to get the vesafb on boottime. Because, there is no longer a bootsplash :(
Stefan means, I need an CLE266 fb kerneldriver and it should work, but via offered a kernel modul, only
Where can that module be found?
The sources for CLE266 Unichrome integrated graphics
Kernel 2.4.x and 2.6.x
http://www.viaarena.com/Driver/linux-fbdev-kernel-src_20050726.tgz
There are some other sources available for different chipsets.
You won't easily be able to use the vesa
framebuffer, because linuxbios always sets a text mode instead of a graphics mode (and the vesafb driver does bios calls in some circumstances, at least on x86, but that can easily be patched)
LinuxBIOS should offer a way of getting the machine right into graphics mode and provide the framebuffer address and depth in the linuxbios table. ;) I say, drop text mode (as an option) and go framebuffer. This allows using two graphics cards on the bios level since we don't need to cope with concurrent mapping of legacy bios areas anymore.
Great idea :D
