Subject: [PATCH] i810fb: Fix console switch regression

From: Stefan Bauer <stefan.bauer@...tu-chemnitz.de>

Commit eaa0ff15c30dc9799eb4d12660edb73aeb6d32c5 ("fix ! versus & precedence in 
various places") introduced a regression in console switching when using 
i810fb. Every 5th to 10th console switch causes 'pixel waste' - the same line 
of multi-colored pixels repeated over the whole screen.
This reverts eaa0ff1 for i810_main.c.
