It is so strange - it certainly doesn't happen on all 64 bit machines - it 
doesn't on my opteron (even without your patch):

[root at athena ~]# grep "SSL parameters" /var/log/m*log*
/var/log/maillog.1:Jan 16 19:10:43 athena dovecot: SSL parameters regeneration completed
[root at athena ~]# uname -a
Linux athena.riede.org 2.6.15-1.1826.2.10_FC5 #1 SMP Wed Jan 11 18:13:37 EST 2006 x86_64 x86_64 x86_64 GNU/Linux
[root at athena ~]# egrep "ssl_(cer|key_f|para)" /etc/dovecot.conf
ssl_cert_file = /etc/pki/dovecot/dovecot.pem
ssl_key_file = /etc/pki/dovecot/private/dovecot.pem
#ssl_parameters_regenerate = 168
