I think this can be written as:

#ifdef CONFIG_X86
# include <asm/sysfb.h>
#endif

also ... the dependency on a large, unrelated option like CONFIG_X86 
looks pretty ugly here - is there no other, more specific CONFIG_ 
option that can be used here - such as CONFIG_FB_SIMPLE or 
CONFIG_X86_SYSFB?

Ditto.

Thanks,
