startx takes very very long time (about 10 min)

[Abdurixit Abduxukur <ABDUXUKUR ABDURIXIT T-SYSTEMS CH>]

Hi there

Recently I have installed RedHat Desktop on Fujitsu-Siemens Celcius R610 PC
for a project which needs 5 monitors. 
On PC I have 1GB Memory and 2 Matrox G450 MMS PCI cards. After RHDT
installation, I did download latest mga driver from www.matrox.com/mga and
installed it. Then I used "insmod agpgart" and "insmod mga" commands to
insert modules. 
Afterwards, I did connect 4 monitors on first Matrox card and fifth monitor
on the second card. I did configure my /etc/X11/XF86Config accordingly. But
startx takes very, very long time (about 10 minutes), X uses 99.9% CPU, but
it does not need more than 5% when it is startup. 
I did make several tests: If /etc/X11/XF86Config includes only 1-2 screens,
X starts up immediately, it is also not very slow with 3 screens, but it is
really slow with 4,5 screens. 

Any Ideas? 

Thank you.

PS: I included my /etc/X11/XF86Config:
