Problems with X on Dell Inspiron 5100?

Is anybody using X and -CURRENT on a Dell Inspiron 5100?  I've spent
the last couple of days trying to get the *(&*&* to work, and I'm
still having a lot of trouble.  X dies with a SIGSEGV:

(II) RADEON(0): initializing int10
(==) RADEON(0): Write-combining range (0xa0000,0x20000) was already clear
(==) RADEON(0): Write-combining range (0xc0000,0x40000) was already clear
(WW) RADEON(0): Bad V_BIOS checksum
(II) RADEON(0): Primary V_BIOS segment is: 0xc000
(==) RADEON(0): Write-combining range (0x0,0x1000) was already clear
(--) RADEON(0): Chipset: "ATI Radeon Mobility M7 LW (AGP)" (ChipID = 0x4c57)
(--) RADEON(0): Linear framebuffer at 0xf0000000
(--) RADEON(0): MMIO registers at 0xe0100000
(==) RADEON(0): Write-combining range (0xe0100000,0x80000) was already clear
(--) RADEON(0): VideoRAM: 16384 kByte (64-bit DDR SDRAM)
(==) RADEON(0): Write-combining range (0xe0100000,0x80000) was already clear
(II) RADEON(0): CloneDisplay option not set -- defaulting to auto-detect
(II) RADEON(0): Primary Display == Type 2
(II) RADEON(0): Panel ID string: ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ
(II) RADEON(0): Panel Size from BIOS: 65535x65535

   *** If unresolved symbols were reported above, they might not
   *** be the reason for the server aborting.

Fatal server error:
Caught signal 11.  Server aborting

This happened when I ran X -configure.  The same laptop works fine
with Knoppix (CD-based Linux distro), so I took the Knoppix config
file and tried that.  Modulo a couple of minor differences it happened
again.  It also happens both with 4.2.1 and 4.3.0

The corresponding Knoppix output at this point was:

(II) RADEON(0): initializing int10
(II) RADEON(0): Primary V_BIOS segment is: 0xc000
(--) RADEON(0): Chipset: "ATI Radeon Mobility LW (AGP)" (ChipID = 0x4c57)
(--) RADEON(0): Linear framebuffer at 0xf0000000
(--) RADEON(0): MMIO registers at 0xe0100000
(--) RADEON(0): VideoRAM: 16384 kByte (64-bit DDR SDRAM)
(II) RADEON(0): Primary Display == Type 2
(II) RADEON(0): Panel ID string: G08303141XD
(II) RADEON(0): Panel Size from BIOS: 1024x768

Somehow it looks as if FreeBSD isn't reading the Video BIOS parameters
correctly.  Has anybody seen this and done something about it?  I'll
continue playing around, but it would be nice to hear of some solution
close at hand.
