This patch fixes up a couple mistakes I made with the i82810 and mew-vw to make
the system boot to a command line.
This patch comments out the code to set up the vga framebuffer to allow
the system to boot, without this fix the system hangs during elfboot.
The only line that is absolutely necessary to change is the SMRAM setup,
however I've commented out all vga setup to make it very obvious to both
the kernel/payload and anyone looking at the code that vga isn't
currently working. This setup might also be better handled in
northbridge.c, if it doesn't need to be done before ram init, yet
another reason to comment it all. In the future, LinuxBIOS needs to be
told that the graphics memory area, 1mb or 512kb (at the user or
developer's option), is reserved for the onchip vga, but I'm not sure if
it's taken at the top or bottom of the memory, yet. LB may also need to
set a base address for the AGP aperture and/or be told that range is
reserved as well, whether this was originally the job of the system bios
or vga bios is still a mystery. It also corrects the number of entries
in irq_tables.c, without this fix the kernel would probably complain and
hang due to unmapped IRQs.
