Well.. KLD? :)
Thats about as close as it gets. You would have to reload the KLD each time
you wanted to change it.. Yech.
IMHO Mike is right, its not something FreeBSD is geared towards because of
interrupt latency. The KLD idea *could* work depending on what you wanted to do.

Well depends on your definition of 'bad'.
No paging in the kernel, which would be kind of wasteful :)
Go look at GGI for stuff about kernel gaphics drivers.
