As far as I can tell, rpm doesn't know any distinction between i586 and 
i686 versions (at least for dependencies).

Not surprising. :-)

kernel  i586

However, this message in dmesg:
snd_sb16: version magic '2.6.7-1.437.1.ll.rhfc2.ccrma preempt 686 
REGPARM 4KSTACKS gcc-3.3' should be '2.6.7-1.437.1.ll.rhfc2.ccrma 
preempt 586 REGPARM 4KSTACKS gcc-3.3

led me to check the modules and sure enough:
vermagic=2.6.7-1.437.1.ll.rhfc2.ccrma preempt 686 REGPARM 4KSTACKS

I did that and yes it works.
Thank you.
