On T60 with Libreboot 20231106 and the GRUB payload, a user
reported this error in GRUB when a battery was connected:
"alloc magic is broken at 0x7b1aedf0: 0"
This error disappears when a battery is not connected, or
when using Libreboot 20230625. The issue has persisted
through to LIbreboot 20240225 and after, and I believe the
issue will be somewhere in coreboot, not in GRUB itself.
For now, switch i945 laptops (X60, T60, Macbook2,1) back to
the February 2023 coreboot revision used in Libreboot 20230625.
A bisect can be done before the next Libreboot release, ETA
May 2024, if time permits. Otherwise, this revert should solve
the problem for now, at least so far as Libreboot is concerned.
The following coreboot patches have been backported:

drivers/pc80/rtc/option.c: Stop resetting CMOS during s3 resume
Further patches from upstream:
commit 432e92688eca0e85cbaebca3232f65936b305a98
Author: Bill Xie <persmule@hardenedlinux.org>
Date: Fri Nov 3 12:34:01 2023 +0800
drivers/pc80/rtc/option.c: Reset only CMOS range covered by checksum
These patches fixed S3 on GM45 machines, though it will be useful on
the i945 machines aswell.
The reason I'm doing it this way it is because I don't have a battery
for my X60 or T60, and my T60 isn't in a very good state either,
so I can't reproduce the error myself yet.
