I got 1024x768x8 display for my Toshiba Tecra 720CT notebook.

Used vga controller is hiqvideo, and the /lib/vgadb around there is like:

ctlr
	0xC0090="CHIPS 65550 PCI & VL Accelerated VGA BIOS"	# NEC Versa 6030X/6200MX
	0xC0090="CHIPS 6X554 PCI Accelerated VGA BIOS"	# Digital HiNote Ultra 2000
	0xC0090="CHIPS 69000 PCI Accelerated VGA BIOS"	# Rackmount
	0xC0090="TOSHIBA Video BIOS V2.30"				# Toshiba Tecra 720CT
	link=vga
	ctlr=hiqvideo linear=1
	hwgc=hiqvideohwgc

and added monitor section as:

#
# XGA (Laptop).
#
xga = 1024x768
	include=1024x768
xga
	alias=svga
#

#Tecra 720
#
tecra = 1024x768
	include=1024x768@60Hz
tecra
	alias=svga
#
# LCD
# Just a convenience, really.
#

Yes, 1024x768@60Hz worked fine.

Now I can come home soon, because I don't harry about FDD problem.
I have CD-ROM drive in this notebook.  :-)
