Yes, as soon as I saw how small the actual patch was that the openssh team
provided I decided that it is actually easier to patch the openssh-2.9
version than to try to upgrade openssl without knowing what might break.
On RH 6.2 (dalton):
# rpm -e --test openssl
error: removing these packages would break dependencies:
openssl is needed by libpcap-0.6.2-18.104.22.168

Strangely enough apache does not appear at all! Inquiring a little bit more:
# rpm -qR apache
rpmlib(PayloadFilesHavePrefix) <= 4.0-1
# rpm -qf /lib/libcrypt.so.1
Thus it seems that apache does not even use openssl?? I did not know this.
Anyway - it just looked easier to patch than to upgrade openssl.
There also is a large patch required in order to use openssh-3.4p1 for
2.2 kernels (which you can pull out of the Mandrake src.rpm that they released
yesterday). All of that does not seem to be worth the effort.
Sorry for causing you to go through the pain of upgrading/downgrading
