Well, I tried out the Halsign drivers. The Windows license is confusing. It 
appears parts are GPL, parts are not. It's not clear which is which.

The structure of the drivers is very similar to yours. Scsi drivers, a new 
network interface, and various system devices (a bus device and a 'comm' 
device). For some reason, I have a second cdrom device in My Computer, even 
tho' I only defined one in my config.

Both network interfaces are active the first time you boot into his '/pv' 
version of the os, and you have to disable the slower 100MB one, leaving the 
1Gb one active. Both Qemu and scsi devices seem to be active, but a system 
msg in the event viewer from PartMgr reads 'Disk 0 will not be used because 
it is a redundant path for disk 1.', so maybe he got around having both 
active another way. No corruption so far, but it's early yet :-)

The 1Gb network interface is about twice as fast as the 100Mb one in my domu 
to dom0 file copy, and no BSOD. An intra domu file copy was the same on both 
booting w/ /pv and w/o. However, I had to find space on nfs for the test 
system, so I was not really expecting a speedup there, and this would not be 
a fair test of the scsi drivers.

The guest portion drivers installed w/o the host service having been installed 
yet. I did install the host portion later, and I still don't see it's point.
