 This is what he's getting at.  If he could get access to 128 bit fp,
 he could move between 1/2 and 2/3 of the work into hardware operations
 and bypass a large chunk of GMP work which would be many many times
 slower than 128 bit hardware FP.

You make it sound as though 128 bit hardware FP exists.
Bruce's point (I'm fairly certain) is that there's no such thing
(at least in the x86 world: could be different in IBM Power
series, not sure.)  Have I missed a press release or tech doc?
AVX, just like SSE{2,3,4} only does 64-bit double: everything
else is software.

  Booting the DL145 G3 with disabled ehci in GENERIC kernel changes =
  nothing, the boot process still times out with
  mount waiting for: usbus1 usbus0

Hmm, if you are still able to try, it would be interesting to build a kernel 
without USB at all to see if it can boot ok.  Also, it might be good to break 
into DDB in a kernel with USB enabled and run 'show intrcnt' to see if the USB 
devices are seeing any interrupts.
