[CentOS] Installing kernel RHEL-5.3 on CentOS 5.2 (x86_64)

Hi

I tried to install the kernel Red Hat 5.3 x86_64 (2.6.18-128.el5.x86_64) 
with the command:
  rpm -Uvh kernel-2.6.18-128.el5.x86_64.rpm
but there is problem with dependecy: ecryptfs-util < 44. How to solve 
problems with depencies when installing a beta kernel?

I'm trying this kernel to see if I get CentOS working with the wireless 
iw4965. I tried the drivers from Intel, but the compilation failed.

Thanks

Marcelo
