[PATCH] i810fb: Change option ext_vga to extvga to match documentation
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.
