I'm installed. Made a custom boot floppy with the plan9.ini from plan9.iso's boot.img. In addition, one of either *noe820scan=1 or *norealmode=1 were required to avoid the freeze-up mentioned throughout this thread. The floppy's boot menu points to kernels on the plan9.iso that is configured as the IDE secondary master.
Taking another cue from Jack's experiences, I asked for the NIC to be configured as a RTL8139. With either option (*noe820scan or *norealmode), my installed system can't pass icmp or tcp traffic to hosts on the local network. Networking is configured as normal (in fact, the configuration is identical to the Plan9 in qemu I had working on this same hardware under KVM/qemu -> OpenBSD -> kqemu/qemu -> Plan 9). After booting, the contents of /net/iproute, ip/ndb, etc., seem correct and are consistent with my other, working, Plan 9 systems. The new system can ping it's own IP address, but cannot be pinged from the local network. I suspect there may be some sort of arp confusion in the ethernet switch. This system was previously configured with the same IP address, bridged from kqemu/qemu to the kqemu/qemu host's external interface (which itself was a virtual interface hosted on KVM/qemu). With this new configuration, the MAC address has changed. I've submitted a support request to check it out. -sl
