The ACPI IPMI driver implements IPMI operation region support for the
ACPI core. Systems that declare ACPI operation regions may reference

will fail unless the ACPI IPMI driver is present, and undesirable system
behaviour may result. This can be avoided by building in the code rather
than leaving it as modules.
Undesirable behavior how? System crashes, random scribblings on kernel
memory, or just a lack of IPMI support?
I'm not doubting your conclusions, but I'm curious why this is a problem
now when we've had the drivers set as modules for 2 years. I can't
recall any major problems.
