ftp://ftp.linux.org.uk/pub/linux/alan/DMI/dmidecode.c works properly
on my desktop machine, but on the affected laptop it just repeatedly
prints out

DMI 2.3 present.
44 structures occupying 1330 bytes.
DMI table at 0x17FF0000.
dmi: read: Illegal seek

and doesn't say anything interesting.  Both machines are running
vanilla Red Hat 7.2, I think.  Shall I try it with vanilla 2.4.18-rc1?
