:Matt,
:
:While the effort that you put into this problem is without doubt 
:appreciated, I wonder why you chose this approach rather that converting 
:the driver to use busdma?  NetBSD and OpenBSD use busdma, although of 
:course their implementation differs from ours.  The FreeBSD code is 
:already ugly enough since alpha is special cased and I doubt that ia64 
:or sparc64 could possibly work.  And as you point out, your hack still 
:isn't totally correct.
:
:Scott

    I'm just fixing bugs at the moment.  I don't really have time to rewrite
    the code, at least not now (I'm the VM guy, not the device driver
    guy, remember?).  I think it's preferable to fix the bugs verses
    doing nothing at all.
