Looks like the same problem on a desktop:

Never tried this machine with kernel older than 2.6.2. FB VESA works fine. If i use ATI Radeon (does'n matter old or new) the screen goes dark until i start X. With the new driver i found in dmesg:
[...] Kernel command line: root=/dev/hda1 vga=0x31a [...] PCI: Using ACPI for IRQ routing PCI: if you experience problems, try using option 'pci=noacpi' or even 'acpi=off' radeonfb: cannot map FB SBF: Simple Boot Flag extension found and enabled. SBF: Setting boot flags 0x1 [....]
Compile warnings with new driver:
[...] drivers/video/aty/radeon_base.c: In function `radeon_probe_pll_params': drivers/video/aty/radeon_base.c:474: warning: `xtal' might be used uninitialized in this function drivers/video/aty/radeon_base.c: In function `radeon_screen_blank': drivers/video/aty/radeon_base.c:944: warning: `val2' might be used uninitialized in this function drivers/video/aty/radeon_base.c: In function `radeonfb_setcolreg': drivers/video/aty/radeon_base.c:1025: warning: `vclk_cntl' might be used uninitialized in this function CC net/sunrpc/timer.o drivers/video/aty/radeon_base.c: In function `radeon_calc_pll_regs': drivers/video/aty/radeon_base.c:1319: warning: `pll_output_freq' might be used uninitialized in this function [...]
