Changes in siimage driver?

I've noticed that the siimage driver has changed since a few revisions
back, I ran into some problems probably related to the driver when
updating to 2.6.0-test5-mm1 however. First of all, I noticed hdparm
reported really bad performance numbers for my Maxtor DiamondMax9 120GB.
About 16MB/sec is reported for a buffered disk reads. The older version of
the driver doesnt turn on DMA, but after enabling certain options (-d1,
X66 etc.) with hdparm, I get ~50MB/S. It's not an ideal solution since now
and then I get a bunch of "disabling irq #18" messages after running
hdparm (I think, its part of the startup scripts), and I have to restart.
The second issue is more serious; after rebooting I noticed 3 files I had
been working on, and a couple of directories I had downloaded were
corrupted. The single files were filled with zeros, while the directories
were impossible to access (I/O error). I couldn't even rm (-r) the
directories. Am I the only one who's run into any sort of issues with the
updated driver? From what I can see it hasn't been modified in the last
revision (test5-bk4), hopefully noone is losing important data because of
this (fortunately I had some recent backups). Anyway, I'd like some
feedback on this from those in the know (the performance drop should be
fairly easy to verify, unless hdparm is playing tricks on me).
Thanks in advance
