svn commit: r287934 - head/sys/boot/efi/loader

[Rui Paulo]

No, that doesn't work very well.  Not only the modules don't auto-load, the way the modules are compiled is different.  See, for example, cam ctl which doesn't compile the sg code when it's built into the kernel, but compiles it when it's built as a module.  The sg code is currently buggy and causes insta-panics with GNOME 3 (perhaps the auto-mounter in hald (?)).
