linux-2.4.22-pre5 drm/agpsupport unresolved symbols

[James Bourne]

The attached patch fixes the following compile error when building
agpsupport as a module.  This is against 2.4.22pre5.

Marcelo, please apply as it's a very simple patch the adds the symbol to an
enum in include/linux/agp_backend.h and adds a missed break statement in
drm-4.0/agpsupport.c.
