+Subject: [PATCH] Revert "sdlaudio: make it suck less"
+
+This reverts commit 4839abe78fd466a3cf06faa7c362154afd5404f1.
+
+The commit was badly broken, Gentoo has sdl as the default driver,
+consequently 5 gentoo users have hit the breakage and were kind enough
+to report, so thank you:
+
+Claes Gyllenswrd
+vekin
+Chris
+
+But above all thanks to Toralf Foerster who actually provied enough
+information to pinpoint the breakage to sdlaudio.
