unable to install revo in php 5.1.6 server =>why revo wont support this version

hello
iwas trying to install revo beta 5 in my clients server
server php version 5.1.6
mysql version

from the docs i came to know that revo wont install in php 5.1.6 servers
but can anyone tell me the reason for not supporting in php version 5.1.6

sorry i have to inform my client about the problem with version 5.1.6
i did all my development work with revo in my local server ,i have to upload this to server

Thanks

Due to bugs in the PHP 5.1.6 PDO drivers, it can cause Apache segfaults, dropped connections, and other malevolent behaviors.

hello
i have installed modx revo Beta5 in the server successfully
but i was not able to log into manager
after i hit the login button its only displaying loading box and not logging in actually
i checked with firebug error console
find a json error response
"<b>Fatal error</b>: Class name must be a valid object or a string in <b>/.../.../core/model/modx/modx.class.php</b> on line <b>1095</b>

"
see the screenshot here

Thanks

1) Check the permissions on the cache directory (and others per the install instructions)
2) If you have chmod 777 the folders try chmod 755 instead (suexec)
3) Try another web browser / dump browser cache. Firefox is sensitive in the domain names inside the cookies. This should not be an issue if you do not already have a cookie cached for that domain.
4) If you have changed or placed an .htaccess file in the root or /manager folders rename it to ht.access until you get things sorted out
5) Make sure your php is running with enough memory
6) Make sure MySql is functional and accepting connections

Any one, combination of some of these, or even all of these should help you get into the manager.
