Inspiron 8000: I upgraded the LCD panel, but it didn't "take"

   I upgraded my LCD panel from SXGA+ (1400x1050) to UXGA (1600x1200).
   Unfortunately, my laptop is still running at 1400x1050, so the video
   wraps over at the bottom right edges of the screen.  According to
   XFree86, I still have the IBM panel installed rather than the Samsung
   UXGA panel:

   (II) R128(0): Video RAM override, using 32768 kB instead of 32768 kB
   (**) R128(0): VideoRAM: 32768 kByte (128-bit SDR SGRAM 1:1)
   (**) R128(0): Using flat panel for display
   (**) R128(0): Will try to use DMA for Xv image transfers
   (II) R128(0): Panel size: 1400x1050
   (II) R128(0): Panel ID: IBM ITSX68E             
   (II) R128(0): Panel Type: Color, Single, TFT
   (II) R128(0): Panel Interface: LVDS
   (II) R128(0): PLL parameters: rf=2700 rd=12 min=12000 max=27000; xclk=10500

   Any thoughts?

I eventually got it working under X only, through some rather ugly
incantations.  In addition to explicitly setting the width and height
of the panel, I also had to set use_fp_regs to off in my XF86Config.
