Subject[PATCH] ipmi-remove-invalid-acpi-register-spacing-check
At the 2.6.12 timeframe ipmi_si_intf.c was patched to provide
default register spacings in try_init_acpi() if the register
spacing was set to zero, similar to code in other routines.
Unfortunately, another patch was simultaneously added that
exits early from try_init_acpi() if the register spacings
are set to zero, circumventing the new defaults. This patch
removes the early exit code and some incorrect comments that
aren't present in other common code snippets.

Without this fix, several systems will not work correctly.
