I ran a limited test with the new code to see what works.  All tests run
with kqemu enabled binary (1.3.0pre9).  Host is a laptop w/ pentium 3
mobile processor running ubuntu linux.

deb-sid (2.6.17-1-686 SMP):

qemu -hda deb-sid.qcow -no-kqemu
   boots to login prompt

qemu -hda deb-sid.qcow
    boots to login prompt

qemu -hda deb-sid.qcow -kernel-kqemu
    hangs on boot with:
       
  hda: QEMU HARDDISK, ATA DISK drive
  ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
  hdc: QEMU CD-ROM, ATAPI CD/DVD-ROM drive
  ide1 at 0x170-0x177,0x376 on irq 15
  hda: max request size: 512KiB
  hda: 6291456 sectors (3221 MB) w/256KiB Cache, CHS=6241/255/63, (U)DMA

  hda: set_multmode: status=0x41 { DriveReady Error }
  hda: set_multmode: error=0x04 { DriveStatusError }
  ide: failed opcode was: 0xef
  ... hangs ...

qemu -hda deb-sid.qcow -kernel-kqemu -no-acpi
   boots to login prompt

I also tried an old fedora core 5 install iso 'FC-5-i386-disc1.iso'
since it uses a 2.6 kernel:

qemu -cdrom FC-5-i386-disc1.iso -kernel-kqemu
   hangs on boot with:

  hdc: QEMU CD-ROM, ATAPI CD/DVD-ROM drive
  ide1 at 0x170-0x177,0x376 on irq 15
  ide-cd: cmd 0x5a timed out
  hdc: lost interrupt
  ide-cd: cmd 0x5a timed out
  hdc: lost interrupt
  hdc: ATAPI 4X CD-ROM drive, 512kB Cache
  Uniform CD-ROM driver Revision: 3.20

  it will boot appending -no-acpi.  For whatever reason the images will
boot with qemu on windows host without problem.
