For 256 color more the first priority is to find out why direct

decision (in hw/*vga.c) and seeing if it's right or not.
I think this is because A000 is not initialized for KVM (see log below
and logging patch attached).
Why isn't it initialized?
Did the guest configure things such as it is impossible to map it
directly? Or does the configuration allow direct mapping and qemu
incorrectly decides that it cannot direct map?
Best would be to print out all the configuration registers and interpret
them according to the specification.

Do not meddle in the internals of kernels, for they are subtle and quick to panic.
