2007-05-08i810fb: fix incorrect frequency maskAntonino A. Daplas1-1/+1
Fix a long-standing bug. The mask used to detect a 100Mhz or 133Mhz chipset is incorrect. (The only side effect of this bug is that it will choose an incorrect watermark).

Allow the saving and restoration of VGA text mode. The state is saved on the first open and restored on the last close. Because of the VGA registers are linearly mapped to the MMIO space, MMIO access is used which is not limited to X86 platforms nor to the primary display device.

2007-05-08fbdev: don't show logo if driver or fbcon are modularAntonino A. Daplas2-2/+19
It was always intended for the logo to be drawn only if both fbcon and the driver that is mapped to it are both compiled statically. Currently, if fbcon is loaded prior to the driver, the logo is not shown. Reverse the order, and the code may attempt to draw the logo which is __initdata. By accident, this bug is rarely seen because this method of loading the modules is not common and secondly, a code in fb_prepare_logo() that checks the height of the logo (now a random value) rarely succeeds. Fix by drawing the logo only if both fbcon and the driver are statically compiled.
