Intel Extreme, not usable at 1680x1050, nightly hrev46464

Description
My monitor supports 1680x1050 resolution natively, but whatever Haiku sets the card to it reports "Out of range", or "No Signal". I'm currently using 1280x1024, which works but looks funny.

manually setting DPLL_A (0x6014) to toggle bit DPLL_VGA_MODE_DIS seems to solve the problem

Fixes 1680x1050 (for me) on VGA output. Not well-tested.

This makes sense. Applied in hrev46747.
Note:
See TracTickets
for help on using tickets.
Under Ubuntu 12.04, the current modeline is:
This appears to match up well with the mode reported in syslog line 1907: 1907 KERN: clock=146.25 MHz 1908 KERN: h: (1680, 1784, 1960, 2240) 1909 KERN: v: (1050, 1053, 1059, 1089)
Round about line 6400 of syslog you can see the attempts to set the video mode.
