Yes. gPXE + istgt can be used. I have confirmed with Windows before.
Now I tested with FreeBSD 8.1+isboot0.1.3 (integrated).
If you use integrated version, you can install FreeBSD to iSCSI target,
mentioned in http://www.etherboot.org/wiki/sanboot/iscsi_install.
There is the log of my old machine which have Intel Fast Ether onboard.
(use gPXE1.0.0 FD + FreeBSD-8.1-RC1-i386-isboot-0.1.3.iso)

Notes:
You have to configure DNS (/etc/resolv.conf) and hostname manually.
Or must set exactly matched IP/mask/route in iBFT by sysinstall.
This is current limitation. (sysintall breaks booted NIC parameter.)
