GFS is priced to compete with Veritas, Poliserve, etc. It is not priced 
to compete with an all-you-can eat license from MS. GFS is a complex 
product (with complex support/certification requirements). If you dont 
need the support/certification, CentOS-based GFS/RHCS is a very 
attractive option.

No - a GFS-kernel version maps to a specific kernel version (at least on 
RH it does). the GFS-kernel to kernel version mapping:
GFS-kernel-smp-2.6.9-60.1 goes with 2.6.9-42.0.2.ELsmp
GFS-kernel-smp-2.6.9-60.3 goes with 2.6.9-42.0.3.ELsmp

I think you are getting confused. the GFS package is the userland tools 
(fsck, mkfs) and init scripts. the GFS-kernel* package is the kernel 
modules and is associated with a specific kernel. GFS-6.1.6-1 does not 
install anyhthing into any specific kernel version modules dir, and does 
not require a specific kernel version.

That is VERY strange. Look carefully and you should see a kernel 
version. Mine shows me:

  rpm -qpl GFS-kernel-smp-2.6.9-60.3.i686.rpm
/lib/modules/2.6.9-42.0.3.ELsmp/kernel/fs/gfs
/lib/modules/2.6.9-42.0.3.ELsmp/kernel/fs/gfs/gfs.ko
/lib/modules/2.6.9-42.0.3.ELsmp/kernel/fs/gfs_locking
/lib/modules/2.6.9-42.0.3.ELsmp/kernel/fs/gfs_locking/lock_dlm
/lib/modules/2.6.9-42.0.3.ELsmp/kernel/fs/gfs_locking/lock_dlm/lock_dlm.ko
/lib/modules/2.6.9-42.0.3.ELsmp/kernel/fs/gfs_locking/lock_gulm
/lib/modules/2.6.9-42.0.3.ELsmp/kernel/fs/gfs_locking/lock_gulm/lock_gulm.ko
/lib/modules/2.6.9-42.0.3.ELsmp/kernel/fs/gfs_locking/lock_harness
/lib/modules/2.6.9-42.0.3.ELsmp/kernel/fs/gfs_locking/lock_harness/lock_harness.ko
/lib/modules/2.6.9-42.0.3.ELsmp/kernel/fs/gfs_locking/lock_nolock
/lib/modules/2.6.9-42.0.3.ELsmp/kernel/fs/gfs_locking/lock_nolock/lock_nolock.ko

In case you missed it, the kernel version is 2.6.9-42.0.3.ELsmp

This is a RH RPM, but a Centos RPM (assuming thats what you use) should 
show you something very similar.

I have asked RH support before if one can mix and match RHCS/GFS kernel 
modules with kernel versions and they strongly recommend against it
