I think this is because the '/compat/linux/bin/rm' from Fedora 7 uses
linux_fstatat64()

$ truss /compat/linux/bin/rm /home/patrick/test
linux_fstatat64(0xffffff9c,0xbfbfe9bd,0xbfbfe600,0x100,0x281c4ff4,0x6)
ERR#78 'Function not implemented'

I've got the same problem with RELENG_7/i386, Fedora 7,
compat.linux.osrelease: 2.6.21.

$ truss acrodread8 :
[...]
linux_mprotect(0x1a000,0x1000,0x1,0x360,0x219176d8,0x6) = 0 (0x0)
munmap(0x20f73000,10515) = 0 (0x0)
linux_set_tid_address(0x21917768,0x2155dff4,0x1,0x21917720,0x2155ded0,0x6)
= 64114 (0xfa72)
<segfault>

I put the complete truss output of acroread8 here :

Let me know if i can help, thanks.
