[Bug 529497] Re: drm: [radeon] no display; out-of-range resolution at Live CD boot

[TJ]

** Description changed:

  Starting x86 Ubuntu Live CD Alpha 3 on a PC equipped with an ATI Radeon
  R200 the kernel mode-setting chooses a resolution the CRT monitor cannot
  support, thus rendering the Live CD session unusable.
  
  In order to capture the boot logging the PC was booted using PXE, TFTP
  and NFS from a Lucid Alpha 3 image and the boot log captured via serial
  port (by adding "console=tty0 console=ttyS0,115200n8" to the PXE kernel
- boot options. (netconsole only captures fragments of the boot log -
+ boot options. netconsole only captures fragments of the boot log -
  another problem there I suspect).

  There are other issues with the drm failing in the attached log but this
  one is the first that needs tackling.
