1. In your patchset the patch fb-radeon-intel.patch  does include
changes to drivers/video/intelfb/intelfbhw.c although in the install
instructions  it is stated that intel drivers do not need to be
The changelog in 0.11 includes these two items.
- patch against intelfb (kernel 2.6.26) to allow for PAL/SCART
video timings. You now can use a regular SCART CRT as display
for linux console.
- fixed a bug in intelfb initialization which sporadically
setup video timing with weirdous values
I guess the installation instructions need to be updated for release
If this is correct I would update the instructions.
2. Well I was going to ask this question on linux-fbdev-devel but did
not do so until I get a reply to my other message.
a) Why is MIN_CLOCK set to 25000 in intelfbhw.h ? What would be the
downside of setting it to 10000?
b) Where do I get information about the registers, like what DPLL_A and
DPLL_VCO_ENABLE is? In the header file some values are assigned to them,
but where is it documented what they mean?
DPLL_A VCO for interlaced mode 800x520 at 50i\n");
OUTREG(DPLL_A, INREG(DPLL_A) & ~DPLL_VCO_ENABLE);
