Don't attempt to reset the state of the flip-flop associated with the
vga attribute controller index or set the enable/'palette address source'
bit when saving and restoring 256 colour vga palette with 0x3c6-0x3c9 as
this does not touch the attribute registers.
When this code was ported from FreeBSD in vga.c rev 1.48 the flip-flop
reset parts were mistakenly made to read 0x3ca instead of 0x3da.
Fixes a problem with VirtualBox where the text mode background was a dim
red colour instead of black after VT switch.
Problem reported by and patch from John Carmack.
ok matthieu@ who notes this also fixes a similiar problem with a KVM /
virt-manager virtual machine.
