[nForce 4 SATA Hotswap]

Tyan's nForce 4 boards seem to be among those that don't handle hot-swap
properly in FreeBSD; the disks disconnect fine, and on attaching FreeBSD
sees the "connect requested", but the disk doesn't get picked up:

 ata4: DISCONNECT requested
 subdisk8: detached
 ad8: detached
 ata4: DISCONNECTED
 ata4: CONNECT requested
 ata4: CONNECTED
 ..

No amount of fiddling with atacontrol detach/attach/reinit brings it
back.  This is at least true of RELENG_6 on a K8WE and the Tyan board in
Sun's new entry-level Opteron rackmount (X2100).
