Yes, the config options are the best way to find out.  The =m indicates
whatever they control is being made into a modules.  The trick is often
then finding the name of the config option from the module that gets
loaded.  These appear to be simple modules consisting of a single file,
and those appear to be the be the correct config options for the modules
in question:

	obj-$(CONFIG_FB_UVESA)            += uvesafb.o
	obj-$(CONFIG_FB_VESA)             += vesafb.o
