SoL can be setup and used quite easily using ipmitool - disabling
IPMI-over-serial is another matter (without rebooting, and entering
the BMC-control bit of the BIOS) - this seemed to work on the
PE1950s which I have access to:

ipmitool raw 0x06 0x40 0x02 0xb8 0x84
ipmitool raw 0x06 0x40 0x02 0x78 0x44

AFAIK this issue was only present on some PE1950s, and was probably a
problem with Dell's production-time automated testing system (IPMI over
serial - not SoL - was set up to carry out various tests, but not turned
off again prior to shipping).
