With the 2.4.7-0.12.1 kernel the Dell C600 laptop (BIOS rev. A03 and A13)

pressing <FN><Suspend>. It works fine with 2.4.7-0.11.1 and below

strace apm --suspend - this time as root!
After much hunting through patches and compiling test kernels... the
linux-2.4.7-dmi.patch had been modified between 0.11.1 and 0.13.1. The first two
new chunks cause the problem.
Patch for 2.4.7-2.5 kernel attached, to remove these two chunks.
