James,
Your patch fixed the PCI wide problem. The attached incorporates
your fix and also fixes the ISA oops. So now all my advansys cards
work.

Changelog:
   - fix PCI wide "use_sg > 0" problem introduced in lk 2.6.7-bk2
   - fix ISA oops (present in all versions of the lk 2.6 series to date)
   - bump version to "3.3K" and add comments
   - fix compilation error when ADVANSYS_DEBUG defined
