Bug#714929: linux-image-3.9-1-amd64: vmwgfx freezes console with gfx_payload

[Bernhard Schmidt <berni@birkenwald.de>]

Package: src:linux
Followup-For: Bug #714929

Some more information.

- It still happens with 3.10-1-amd64 (3.10.1-1) from sid
- Workaround is (next to blacklisting) setting vmwgfx.enable_fbdev=1
  on the kernel commandline, which is probably the same as setting the 
  kernel config option CONFIG_DRM_VMWGFX_FBCON
  - !! When the machine has once successfully booted with enable_fbdev=1,
    !! soft reboots (Ctrl-Alt-Del or /sbin/reboot) do not lock up the
    !! console!
  - the fix does not survive hard reset of the VM or powering it down

So I think just setting CONFIG_DRM_VMWGFX_FBCON would help, unless that 
option is dangerous somehow.

Best Regards,
Bernhard
