I think pathconf is supposed to do that, however I dont remember if it can
query filesize. I have seen only PATH_MAX und NAME_MAX on NFS>=3.

However you can strace that:

# strace getconf NAME_MAX /nfs/home
...
readlink("/usr/lib/getconf/default", 0xbf846ea6, 21) = -1 ENOENT (No such file or directory)
statfs("/nfs/home/", {f_type="NFS_SUPER_MAGIC", f_bsize=16384, f_blocks=3731367, f_bfree=454412, f_bavail=155902, f_files=7725054, f_ffree=7434759, f_fsid={0, 0}, f_namelen=255, f_frsize=16384}) = 0
fstat64(1, {st_mode=S_IFCHR|0620, st_rdev=makedev(136, 1), ...}) = 0
mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xb7f33000
write(1, "255\n") = 4
255

In my example the FreeBSD Server is not returning max filesize..
