Bother, meant to reply to list. Trying again.

Has anyone tried these patches?  I managed to apply the dbus patch to debian dbus-1.2.1-3 and dbus's 
unaligned trap verbiage has been tamed.  Nice.  But hald has decided, presumably because of the 
silence due to dbus's absence:-/, to let fly with tons of unaligned trap messages.  But I can't the 
hal patch to apply cleanly to debian hal 0.5.11-3.  Hal, at line 175, module hald/create_cache.c has:

#define ROUND(len,align) ((len + align - 1) & -align)
#define ROUND32(len) ROUND(len, 4)
#define RULES_ROUND(off) ROUND(off, __alignof__(struct rule))

whereas the patch, hunk 1, has:

-#define ROUND32(len) ((len + 3) & ~0x03)
+#define SZ  (sizeof(size_t))
+#define SZM (SZ - 1)
+#define ROUNDXX(len) ((len + SZM) & ~SZM)

which fails to match because of the ROUND() and the RULES_ROUND() lines which the patch is not 
expecting. Other hunks also fail because of the use of RULES_ROUND() at places the patch is not 
expecting.

To apply the patch is going to need some editing of the code/patch.  If I was feeling brave I would 
give it a go, but wondered if anyone has already got a solution?
