More issues:

* QEMU crash with all working pxe devices:

i386-softmmu/qemu -boot n -net nic,model=pcnet -net user -L pc-bios
qemu: fatal: Trying to execute code outside RAM or ROM at 0x7e6005a8

EAX=00007b52 EBX=9c730001 ECX=54450246 EDX=00000000
ESI=061f0000 EDI=c7300000 EBP=00000000 ESP=00007b88
EIP=7e6005a8 EFL=00000002 [-------] CPL=0 II=0 A20=1 SMM=0 HLT=0
...

This happens only with SeaBIOS, the old BIOS works!
