I got iPXE to work with VBox's virtio driver.  Used a git fetch from 24
January, 2012; followed the instructions on iPXE's website; used a
console.h file that has:

#undef CONSOLE_SERIAL

and a general.h file that has:

/* Virtualbox BIOS needs this for iPXE to work correctly */
#define NONPNP_HOOK_INT19

/* Not using PXE menus since they are limited to TFTP-only */
#undef PXE_MENU

/* Dump Fibre Channel and Inifiniband functionality */
#undef FCMGMT_CMD
#undef NET_PROTO_FCOE
#undef SANBOOT_PROTO_FCP
#undef SANBOOT_PROTO_IB_SRB

/* No need for SAN boot functionality */
/* Virtualbox has its own iSCSI initiator */
#undef SANBOOT_PCBIOS
#undef SANBOOT_PROTO_ISCSI
#undef SANBOOT_PROTO_AOE

/* Unwanted download protocols */
#undef DOWNLOAD_PROTO_HTTPS
#undef DOWNLOAD_PROTO_FTP
#undef DOWNLOAD_PROTO_TFTM
#undef DOWNLOAD_PROTO_SLAM

/* Unwanted image type support */
#undef IMAGE_MULTIBOOT
#undef IMAGE_COMBOOT
#undef IMAGE_AOUT
#undef IMAGE_WINCE

and built for virtio-net.

Obviously I had to cut out quite a bit of stuff to get the ROM size down to
where Virtualbox would load it....
