Thinkpad Wide

Does IBM ThinkPad T41 support 1680×1050 external monitor?
My IBM ThinkPad T41 has ATI Radeon Mobility 9000 video card (32MB). The LCD panel is 1400×1050. I want to buy a wide screen 1680×1050 external LCD monitor, but don’t know if my laptop supports such resolution. I couldn’t find useful info at ATI website.
Seems like the highest resolution it can display is 1024×768. It can support resolutions up to 2048×1536 in panning mode whatever that means. Look all the way at bottom of page to see video specs. Hope this helps.
