        I just tried that and it still doesn't work.  For what it's
worth, the debug messages now say:

radeonfb_pci_register BEGIN
PCI: Enabling device 00:0d.0 (0086 -> 0087)
radeonfb: ref_clk=2700, ref_div=67, xclk=16615 from OF
radeonfb: probed DDR SGRAM 32768k videoram
radeonfb: detected DFP panel size: 1280x1024
hStart = 1280, hEnd = 1424, hTotal = 1720
vStart = 1025, vEnd = 1028, vTotal = 1066
h_total_disp = 0x9f00d6^I   hsync_strt_wid = 0x1204fa
v_total_disp = 0x3ff0429^I   vsync_strt_wid = 0x30400
post div = 0x2
fb_div = 0x218
ppll_div_3 = 0x10218
ron = 1792, roff = 22064
vclk_freq = 10800, per = 788

        Okay, I will watch for it.  Thanks.
