[elrepo] kmod-alsa vs RHEL5.3

[Toth Csaba]

Dear Listmembers,

I tried to install RHEL5.3 to a machine with a motherboard sound card 
not supported by RHEL5.3 (it's an Intel PantherPoint, lspci shows 
8086:1e20 as device ID). The install CD installed 
kernel-PAE-2.6.18-128.el5.i686.

I thought I might give a try to kmod-alsa found in elrepo.org but 
kmod-alsa requires kernel(rhel5_kernel_u4) and my kernel provides only 
kernel(rhel5_kernel_u3).
Is there a way to install kmod-alsa to my RHEL5.3? (does rhel5_kernel_u4 
imply it requires RHEL5.4?)

Thanks in advance,
     Csaba
