Resurrect Intel740 driver: i740fb
PATCH v5 1/1 Resurrect Intel740 driver: i740fb
This is a resurrection of an old (like 2.4.19) out-of-tree driver for Intel740 graphics cards and adaptation for recent kernels. The old driver by Andrey Ulanov is located at: http://sourceforge.net/projects/i740fbdev/files/
This is a new driver based on skeletonfb, using most of the low level HW code from the old driver. The DDC code is completely new.
The driver was tested on two 8MB cards: Protac AG240D and Diamond Stealth II G460.

- added Kconfig dependency on FB_DDC
- cleaned up i740_calc_vclk()
- fixed SDRAM/SGRAM detection
- fixed wrong colors in 16bpp mode when neither 555 nor 565 specified
