I've just repeated this this test with syslog only. After letting it go for ~5 min. I couldn't break it with any keys for at least next 10 min., and I turned the power down. Then the same but with this sched.c patch reverted: ^C worked after a few seconds. It looks like time can really matter here. So, maybe it's again something accidental, I don't have another box around to stay idle while repeting this test, but it seems this could be not the best way to compare anything with 2.6.24 or older.
