Urgh, I can't figure out what tickles it reliably.

There is at least another buglet (?) though, if you don't put a slash on
the end of your M=, you lose the subdir path.

[root@...athon-01 linux-2.6.18.x86_64]# make M=fs/ext3/ modules_install
  INSTALL fs/ext3/ext3.ko
  DEPMOD  2.6.18-8.el5
[root@...athon-01 linux-2.6.18.x86_64]# find /lib/modules/`uname
-r`/extra* -name ext3.ko
/lib/modules/2.6.18-8.el5/extra/fs/ext3/ext3.ko

[root@...athon-01 linux-2.6.18.x86_64]# make M=fs/ext3 modules_install
  INSTALL fs/ext3/ext3.ko
  DEPMOD  2.6.18-8.el5
[root@...athon-01 linux-2.6.18.x86_64]# find /lib/modules/`uname
-r`/extra* -name ext3.ko
/lib/modules/2.6.18-8.el5/extra/fs/ext3/ext3.ko
/lib/modules/2.6.18-8.el5/extra/ext3.ko

I'm confused.  Maybe Sam knows how to fix it... :)
