Yes, in the kernel config there are these lines: makeoptions KERNPHYSADDR=0x30008000 makeoptions KERNVIRTADDR=0xc0000000 options KERNPHYSADDR=0x30008000 options KERNVIRTADDR=0xc0000000 options PHYSADDR=0x30000000 options STARTUP_PAGETABLE_ADDR=0x30800000 It's from Andrew Turners config file which he posted on http://wiki.openmoko.org/wiki/FreeBSD in the tarball.
