Patch for KVM86 support on MP kernels

	Hi,

I am probably not knowing what I am doing, but here is my humble attempt
at allowing the framebuffer code to compile (and hopefully work) on MP
machines. I got the inspiration from an earlier unanswered post by Eric
Auge [1], and the current equivalent in OpenBSD [2]. They say there are
probably still problems.

[2] http://www.openbsd.org/cgi-bin/cvsweb/src/sys/arch/i386/i386/kvm86.c

I did not test that code, nor could 100% check that the code is
otherwise equivalent to the version from OpenBSD.

HTH,

So far so good in 640x480 on my IBM T60, with pkgsrc's xorg vesa driver.

Have you tested this with the vesafb(4) framebuffer console driver as 
well?

Cheers,
Jared

It's already enabled in my configuration:
# VESA framebuffer console
options         KVM86                   # required for vesabios
vesabios*       at vesabiosbus?
vesafb*         at vesabios?
options         VESAFB_WIDTH=640
options         VESAFB_HEIGHT=480
options         VESAFB_DEPTH=8
options         VESAFB_PM               # power management support
wsdisplay*      at vesafb? console ?

and here is what dmesg says:
vesabios0 at mainbus0: version 3.0, (C) 1988-2005, ATI Technologies Inc.
 M54CSP
vesafb0 at vesabios0: VESA frame buffer
vesafb0: fb 640x480x8 @0xd8000000
vesafb0: VBE/PM 1.0 [off]
wsdisplay0 at vesafb0 kbdmux 1: console (fb, vt100 emulation)
