hi,
it seems that something is broken:
df -h | grep linux
<above>:/.compat             97G     97G    1.5M   100%    
/dist/local/amd64=FreeBSD_7.0/compat/linux
linprocfs                   4.0K    4.0K      0B   100%    
/dist/local/amd64=FreeBSD_7.0/compat/linux/proc

but

df -hl | grep linux
<above>:/.compat     97G     97G    1.5M   100%    
/dist/local/amd64=FreeBSD_7.0/compat/linux
<above>:/.compat     97G     97G    1.5M   100%    
/dist/local/amd64=FreeBSD_7.0/compat/linux

under 6.x it works as expected:
df -hl | grep linux
<above>:/.compat    150G    150G    1.5M   100%    
/dist/local/i386=FreeBSD_6.2/compat/linux
linprocfs           4.0K    4.0K      0B   100%    
/dist/local/i386=FreeBSD_6.2/compat/linux/proc
