I presume that the new fix should be provided by "xfs: ensure log covering transactions are synchronous", so I tested 2.6.37 patched with it and then 2.6.38_rc1 that has it included.
instead of having xfssyncd write to the drive every 36s, we now have this:

in other words xfsyncd and xfsbufd now alternate at 18s intervals keeping the drive busy with nothing constructive hours after the last write to the drive.
to add to the misfortune, 'mount -o remount ' is no longer able to bring the drive to a quiet state since 2.6.37, so now the only way to achieve an idle drive is to fully umount and then remount the partition.
just for the record, this is a different drive then at the beginning of the thread, and it has these parameters:
meta-data=/dev/sdc1 isize=256 agcount=4, agsize=61047552 blks
= sectsz=512 attr=2
data = bsize=4096 blocks=244190208, imaxpct=25
= sunit=0 swidth=0 blks
naming =version 2 bsize=4096 ascii-ci=0
log =internal bsize=4096 blocks=119233, version=2
= sectsz=512 sunit=0 blks, lazy-count=0
realtime =none extsz=4096 blocks=0, rtextents=0
attached you'll find the trace (with accesses to other drives filtered out).
