No - it would not boot.  It recognizes the ccard and the arrays -
sh dev shows normal looking output, ie
dra0.	DRA0	3 member RAID 5
dra1.	DRA1	3 member RAID 0

but when i try to boot dra0 it error with:
Could not find controller for device dra0
Device dra0 is invalid

I don't know how happy - it complained that a drive was dead, and
rebuilt using the hot spare :(

Nope - card is dead without the two chips.

Terribly :(
I finally aquired a second expander card for my split bus (I had been
running split bus without it just fine), so I took this oportunity to
install it - bad move as this slight change in cabling, and a possibly
bad cable has rendered my arrays unworkable (I'm writing this from a
windows machine :(  ).
A series of foolish moves on my part (marking the failed drive optimal,
restoring the config from backup after the array had already been
rebuilt) has pretty much made them unreadable, unless someone has some
brilliant ideas...
