Some of fb drivers uses atomic_t in bad manner, since there are still some
race-prone gaps.  Use mutexes to protect open/close code sections with
ref_count testing and finally use simple uint.

Detaching fbcon allows individual drivers to be unloaded.  However several
drivers call pci_disable_device() upon exit.  This function will disable the
BAR's which will kill VGA text mode and/or affect X/DRM.

To prevent this, remove calls to pci_disable_device() from several drivers.

Some time before 2.6.15, a third DDC channel was added to i810fb.  On

Reported by: Manuel Lauss <mano@roarinelk.homelinux.net>

He was getting random initial video modes depending on the kernel
configuration.  His option line includes 'extvga'.

The i810fb documentation describes the option 'extvga', however the
driver accepts 'ext_vga'.  Besides 'extvga' being ignored by i810fb,
it also confuses the option parser of i810fb and assigns 'extvga' to
'mode_option'.  This leads to an incorrect video mode at boot time.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
