13 Am I understanding this correctly? vga=0x318 means 1024x768-24@60. Your
14 line calls intelfb with almost the same mode except at 32-bit pixel
15 depth instead of 24. Is this the only change intelfb will make to the
16 video mode? or you end up with 1024x768-24@60 anyway?
17
18 It seems that the mode option of intelfb does not do anything and the
19 mode needs to be set with vga which has specific values.
