I guess it'd make more sense to fix it in the boards firmware, /if/ this is
possible. (I'm wondering what other OSes do in this regard.)

Here is the DMI data, anyway:

$ pwd
/sys/devices/virtual/dmi/id
$ cat board_name
DP55KG
$ cat board_vendor
Intel Corporation
$ cat board_version
AAE47218-403
$ cat product_name

$ cat sys_vendor

$ cat bios_date
10/28/2009
$ cat bios_vendor
Intel Corp.
$ cat bios_version
KGIBX10J.86A.3878.2009.1028.1049


I think I saw a patch for this floating around, but I'm not sure if this made
it into some branch.


  Christian
