[PATCH] DMI patch for broken Dell laptop

[Stephen Rothwell]

Hi Marcelo, Linus,

This adds DMI recognition for anohter broken Dell laptop BIOS (BIOS
version A12 on the Insiron 2500).

Patch against 2.4.19-pre2, but applies also to 2.5.6 (with offset).

Reported by Mihnea-Costin Grigore <mgc8@totalnet.ro>.

  I think this problem exists for all i2500 BIOS versions > A06. (I
have such a machine, and access to the BIOS versions back to A08 if
there is something specific I can test for -- that APM power status
worked with revision A06 is just heresay.)

Thanks for the offer.  The way to test this is to install each BIOS version,
boot into Linux (preferably in single user mode :-)) and then cat /proc/apm.
If you get an OOPS with then it probably has this problem.  The send
the BIOS versions to us and we will add them to the black list.
