A better fix would seem to be to include these functions if
CONFIG_PPC_PMAC is enabled. Otherwise the PM code will surely
not work correctly. Though I'm not sure if that PPC PM
code makes any sense w/o LCD/backlight support anyway.

Hi Ville,
I tried this:
-#if defined(CONFIG_PMAC_BACKLIGHT) || defined(CONFIG_FB_ATY_GENERIC_LCD) || \
-defined(CONFIG_FB_ATY_BACKLIGHT)
+#if defined(CONFIG_PPC_PMAC)
in both atyfb_base.c and atyfb.h, but then there is a build error in
mach64_ct.c when PPC_PMAC is not enabled but FB_ATY_GENERIC_LCD is enabled.
[mach64_ct.c is the only other user of aty_{ld,st}_lcd()]
or did you mean adding CONFIG_PPC_PMAC to that longish #if list?
(that's not how I understood your comment.)
I'll gladly step away and let you submit patches for this. :)

-defined(CONFIG_FB_ATY_BACKLIGHT)
+#if defined(CONFIG_PPC_PMAC)
in both atyfb_base.c and atyfb.h, but then there is a build error in
mach64_ct.c when PPC_PMAC is not enabled but FB_ATY_GENERIC_LCD is enabled.
[mach64_ct.c is the only other user of aty_{ld,st}_lcd()]
or did you mean adding CONFIG_PPC_PMAC to that longish #if list?
(that's not how I understood your comment.)
I'll gladly step away and let you submit patches for this. :)

Yeah, I meant adding ||PPC_PMAC to the existing set of conditions.
You definitely need to have this stuff for the LCD/backlight
support on !PPC_PMAC as well.

I don't have any powerbook/etc. hw to test this so couldn't
really add any extra value. Just have vague memories of touching
this stuff long ago so figured I'd provide my "expertise" :)
