This seems to be a problem with the mount command. Why do you feel the kernel may be at fault? If the kernel can get to mount, then it has obviously already mounted / (though possibly in read-only mode, which is something you should let us know...)
There is also not necessarily a corrolation between a man page and the actual binary. Check the binary's modification time and such for better detail here. Beyond that, try running the mount command manually from the command line after booting from a CD or in single-user mode, if single-user mode works.
