Hi,
I can't get 1680x1050x32 with monitor=vesa: can do either 1680x1050x8
or 1280x800x8.  Attempt to load 1680x1050x32 mode sets the VGA mode
and hangs, displaying just a noise.  Tried the recent 9pc as well as
the ½ yr old one.

Please advice.

The vga is:
3.0.0:	vid  03.00.00 10de/06e4  10 0:cf000000 16777216 1:d000000c 268435456 2:00000000 16 3:cc000004 33554432 4:00000000 16 5:0000e801 128
	NVIDIA Corporation 8400 GeForce 8400 GS

The modes are offered:
vesa mode           0x160 1280x800x8 m8 packed
vesa mode           0x161 1280x800x32 x8r8g8b8 direct
vesa mode           0x168 1680x1050x8 m8 packed
vesa mode           0x169 1680x1050x32 x8r8g8b8 direct

Monitor data (if matters):
edid mfr            PHL
edid name           Philips 220BW
edid product        2150
edid vert (Hz)      56-76
edid horz (Hz)      30000-83000
edid pclkmax        170000000
edid 1680x1050x0@60Hz
		clock=119
		shb=1728 ehb=1760 ht=1840
		vrs=1053 vre=1059 vt=1080
		hsync=- vsync=+

Thank you in advance.
Yaroslav.

when trying (unsuccessfully) to get the nvidia driver working
correctly for my card, i wondered if a few registers weren't
slightly off.  i could be wrong and this was a long time ago,
but fwiw:

	vga->crt[0x04] = mode->shs/8 - 1;			/* differs by -1 */
 	vga->crt[0x13] = (vga->virtx/8)*(mode->z/8);
	vga->crt[0x15] = mode->vt - 1;			/* differs by -1 */

the 0x13 register was a particular problem.  with the normal setting,
the cursor just froze up and wouldn't move.

(correction): can do 1680x1050x8, 1280x800x32.

I can't get 1680x1050x32 with monitor=vesa.  Attempt to load
1680x1050x32 mode sets the VGA mode and hangs, displaying just a
noise.  Tried the recent 9pc as well as the ½ yr old one.
