RE: Intel 82852 - switching LVDS mode to SXGA

Hi, 

Sorry if this is a bit off-topic but I thought I might be able to get some
info here. I have a Toshiba laptop with Intel 82852 integrated graphics and
XGA (1024x768) screen. I'm trying to upgrade it to an SXGA LCD panel. The
82852 chip supports resolutions of up to SXGA+ via LVDS and it can read
panel data so it can adjust the timing parameters accordingly. For some
reason it fails to revognize the new panel and the screen is messed up, even
in text mode. Is changing LVDS signal resolution something that can be done
via device drivers? Or perhaps the chip is programmed at boot time by
Toshiba BIOS to a fixed setting so that such upgrade is not possible? 

Thanks for any info, 
Vlad.

PS: sorry if it is a double-send, I sent one message from a wrong account,
so I'm not sure if it will bounce.
