The problem is still there with 1.0.15rc3 - however, I've found the 
cause of the issue:

EXPORT_SYMBOL(snd_ctl_elem_read) and EXPORT_SYMBOL(snd_ctl_elem_write) 
have been removed from alsa-kernel/core/control.c - see:

<http://hg.alsa-project.org/alsa-kernel/rev/efd5ab99655e>

I guess this is OK for more recent kernels, but still needed for 
RHEL4/CentOS4 2.6.9 kernels

I can work round the problem by putting these back into acore/control.c

I've attached a patch which patches acore/control.patch
