今井です。

件のマザーのデバイスの状況は以下の通り。
(Rev2.0のほうだとまたちょっと違った結果になるかも)

で、本来なら
02:07.0 Ethernet controller: VIA Technologies, Inc. VT6120/VT6121/VT6122 
Gigabit Ethernet Adapter (rev 11)
のところがRTL1111Cとなり、IEEE1394のコントローラも更に追加される。
(オンボードLAN、IEEE1394、パラレル、COMポートは未使用につき無効化してある)

でもって/proc/interruptsで割り込みの状態を見ると

となっている訳ですが、SATAポートの4、5番ポートが独立してSATA(SATAポート0番
から3番までの動作モードに連動)、PATAモードと切り替えられる様になってるため
IRQ 15も使用できる様になってるみたい。
SATAポートの0番から3番までの4ポートも、4、5番ポートとは別にIDE互換、RAID、
AHCIモードへと切り替えられる。

ということでSATA仕様のDVD(BD)-R/RWドライブを使う場合にはSATAポートの4、5番
に繋いだ方が都合が良いかも知れません。
