There is a performance and target mode update in the works, but yes,
the driver is quite stable.

I work for Adaptec.  I can't do anything to help with getting out
documentation though. That policy is set by individuals I have not been
able to sway to my line of thinking.

However, there isn't a single piece of documentation that Adaptec ever
published that would aid in porting this driver to NetBSD.  In otherwords,
the interfaces of interest only have source code documenation.  Much
lesser programmers than those working on NetBSD have ported this driver
to "the random custom RTOS" or other custom system with no documentation other
than the source code and little to no interaction with me.  Don't let the
lack of documenation be an excuse for not upgrading the driver.

My mailbox is always open to questions about the driver, how it works,
bug fixes, improvements, etc.
