Thanks for the explanation.  I'll repost my "DMA"-like fw-cfg patch
once I've rebased it and done some more testing.  This huge regression
for a common operation (implementing -initrd) needs to be solved
without using inb/rep ins.

Adding more interfaces is easy but a problem in the long term. We'll optimize it as much as we can. Meanwhile, why are you loading huge initrds? Use a cdrom instead (it will also be faster since the guest doesn't need to unpack it).
