Hi,
 
I cannot tell  why your kernel is not booting, but I know that kernels 
with greater
ramdisks are booting (also via PXE).
 This is my setup:


# Enable the hooks used for initializing the root memory-disk.
options     MEMORY_DISK_HOOKS
options     MEMORY_DISK_IS_ROOT                       # force root on 
memory disk
options     MEMORY_DISK_SERVER=1                    # no userspace 
memory disk support
options     MEMORY_DISK_ROOT_SIZE=180000    # size of memory disk, in blocks
options     MEMORY_RBFLAGS=0                            # not an 
installation kernel, so boot into
                                                                                  
# multiuser mode,
#options     MEMORY_DISK_DYNAMIC                    # doesn't work with 
prefilled ramdisk
