	I think I had the same question some time ago and found
	out that if those options are present, the Linux functionality
	will build properly in the kernel. So I assume they are
	required.

I removed COMPAT_LINUX, and only left

options COMPAT_43
options COMPAT_LINUX32

This seems enough to get flash
working with firefox, exactly as per
the handbook instructions.
