Is it posible to run FreeBSD/sparc64 on SunFire V215?

Hello!

Is it possible to run FreeBSD/sparc64 on SunFire V215?
This system is similar to SunFire V210/V240/V125, but have PCI-X and SAS disks.

I'm tried to boot 8.0-BETA4, but it hangs after "jumping to kernel entry":

{1} ok boot net
Boot device: /pci at 1e,600000/pci at 0/pci at 9/pci at 0/network at 4  File and args:
100 Mbps FDX Link up
Requesting Internet Address for 0:14:4f:a2:ef:2c
Requesting Internet Address for 0:14:4f:a2:ef:2c
Consoles: Open Firmware console

Booting with sun4u support.

Hit [Enter] to boot immediately, or any other key for command prompt.
Booting [/boot/kernel/kernel]...

As I know, OpenBSD 4.5 works on this platform, and I successfuly booted kernel.
Why FreeBSD isn't ported to v215?
