Why is xorg ignoring the frequencies I give it?

[Miles Lane]

Hello Alan,

It seems that you are the person who added support for the E7221
graphics chip to xorg recently.  Would you please look at this user's
report and suggest a solution?  AFAICT, there are a couple of
problems.  First, Andy's kernel doesn't seem to have a driver for
E7221 agpgart.  Second, there may be some BIOS issue that is
causing the refresh rate to be set incorrectly.  I googled for
others having trouble with "Extended BIOS function 0x5f05 failed"
and "I810(0): BIOS call 0x5f05 not supported, setting refresh with
VBE 3 method" but found nothing helpful.

(--) I810(0): Chipset: "E7221 (i915)"
(WW) I810(0): Extended BIOS function 0x5f64 not supported.
(--) I810(0): HW Cursor disabled because it needs agpgart memory.
(--) I810(0): Maximum frambuffer space: 7912 kByte
(II) I810(0): Will use BIOS call 0x5f05 to set refresh rates for CRTs.
(--) I810(0): Maximum space available for video modes: 7872 kByte
(II) I810(0): Using detected DDC timings
(II) I810(0): 	HorizSync 28-92
(II) I810(0): 	VertRefresh 57-85
(WW) I810(0): config file vrefresh range 43-72Hz not within DDC
vrefresh range 57-85Hz
(II) I810(0): SDM-S204: Using default hsync range of 28.00-92.00 kHz
(II) I810(0): SDM-S204: Using default vrefresh range of 57.00-85.00 Hz
(--) I810(0): Virtual size is 1600x1200 (pitch 1600)
(**) I810(0): *Built-in mode "1600x1200"
(--) I810(0): Display dimensions: (410, 310) mm
(--) I810(0): DPI set to (99, 98)
(--) I810(0): Xv is disabled because it needs 2D accel and AGPGART.
(WW) I810(0): Extended BIOS function 0x5f05 failed.
(WW) I810(0): Extended BIOS function 0x5f28 not supported.
(WW) I810(0): Option "UseFBDev" is not used
(WW) I810(0): Setting the original video mode instead of restoring
	the saved state
(WW) I810(0): Extended BIOS function 0x5f05 failed.
(II) I810(0): BIOS call 0x5f05 not supported, setting refresh with VBE 3 method.
