Not so much to reply to myself, but on second thought, maybe it was |
| 33 |
splashutils/fbsplash that is broken by this. |

| 35 |
Anyway, the point being that there are some modules that seem unrelated, |
| 36 |
but which one might be using, that will break if regparm is set. So be |
| 37 |
careful. |
