17 /* XXX This device has a 'dev-comm' property which apparently is
18  * XXX a pointer into the openfirmware's address space which is
19  * XXX a shared area the kernel driver can use to keep OBP
20  * XXX informed about the current resolution setting.  The idea
21  * XXX is that the kernel can change resolutions, and as long
22  * XXX as the values in the 'dev-comm' area are accurate then
23  * XXX OBP can still render text properly to the console.
24  * XXX
25  * XXX I'm still working out the layout of this and whether there
26  * XXX are any signatures we need to look for etc.

144 /* XXX This is a bit of a hack.  I can't figure out exactly how the
145  * XXX two 8bpp areas of the framebuffer work.  I imagine there is
146  * XXX a WID attribute somewhere else in the framebuffer which tells
147  * XXX the ramdac which of the two 8bpp framebuffer regions to take
148  * XXX the pixel from.  So, for now, render into both regions to make
149  * XXX sure the pixel shows up.
