Perhaps #if defined(CONFIG_VGA_CONSOLE) || defined(CONFIG_FB_VGA16) ?
or
bool VGA_HARDWARE
#if CONFIG_VGA_HARDWARE
unsigned long vgacon_remap_base;
EXPORT_SYMBOL(vgacon_remap_base);
#endif
and for the Kconfig entry of vgacon and vga16fb
select VGA_HARDWARE if PPC32
(or depends on (VGA_HARDWARE && PPC32))
