Sure, we are using CGP 5.2.12, but got this working initially on 5.1.13 running on SuSE linux x86 (rpm based installation). Apache, we are running Apache/2.2.6 on an archaic RedHat installation (6.2 I believe).

Example of this working from our apache access log:

192.168.1.X - - [24/Mar/2009:15:04:23 +0000] "OPTIONS /Microsoft-Server-ActiveSync HTTP/1.1" 200 - "-" "Apple-iPhone/508.11"
192.168.1.X - - [24/Mar/2009:15:04:23 +0000] "POST /Microsoft-Server-ActiveSync? HTTP/1.1" 200 905 "-" "Apple-iPhone/508.11"

and from our CGP log:

15:06:22.258 2 AIRSYNC( iPhone(Appl87842XHVY1K): Sync request
15:06:22.427 2 AIRSYNC( 'INBOX': 1 retrieved, reported 4 as deleted, 0 as updated

Note: Our webserver is 2 minutes out hence the logs being different, NTP has issues on that version of RedHat

The apache config is just setup as previously stated, the ProxyPass, ProxyPassReverse and the SSLProxyEngine lines were the only amendments to our web server that was already setup.

And as a note, apologies for my last email, I mentioned we use self-signed certificates, but I realised we actually have a proper signed certificate for that webserver, we only have self signed on CGP itself. I had read about self signed certificates on the iPhone when reading the iPhone enterprise deployment guide, I think you can just browse to and download the certificate directly on the iPhone using safari.

I mentioned the "/" at the end of the config in my last email, as I am sure that caught me out when initially set this up (but it was a while ago now). Can't think of anything else of the top of my head.

Sorry I can't be of more help for now, if I do think of anything will let you know, this solution is possible, maybe someone else on the list has some experience setting this up?
