[Beowulf] Any industry-standards that allow automated BIOS modifications and dumping? IPMI cannot do it, can it?

sounds like your version of ipmitool is compiled without lanplus
(or misconfigured in some way)

there's no driver here: ipmitool is a user-level network client 
that sends packets to the bmc.  if the bmc isn't running a protocol
like lanplus, ipmitool will just fail to connect (timeout):

[hahn at req773 ~]$ ipmitool -U admin -P whatever -I lan -H cp-req1 chassis status
Get Session Challenge command failed
Error: Unable to establish LAN session
ipmi_lan_send_cmd failed to open intf
Error sending Chassis Status command

> The LAN interface does work file but apparantly "sol activate" needs lanplus.

IMO, they misuse the term 'interface' there - they mean protocol.
