Bingo! Thanks!
Hmm..., but why? I didn't specify noexec for any of my mounted filesystems 
except /proc:

 $ grep noexec /etc/fstab 
 proc            /proc           proc    defaults,noexec,nosuid  0       0

However, 3 of my reiserfs filesystems are mounted as noexec:

 $ mount | grep reiserfs.*noexec | wc -l 
 3

All of them have the following controls in /etc/fstab:

  auto	defaults,users,notail,noatime,nodiratime,barrier=flush

Does that means auto+defaults for reiserfs filesystems are noexec?

or maybe it is "barrier="? Actually two of them have barrier=flush and 
one of them has barrier=1. I vaguely remember from the log that barrier= 
is not supported by reiserfs but I didn't care about it before. 

Please help.

Thanks
