Don't think so - seems to be a real dependency problem.

Not at work right now to supply the exact error, but I did try "rpm
-e ...".  That's what I meant by "This causes yum to want to remove
needed packages, or rpm to complain about dependencies." above. The rpm
erase failed due to the unsatisfied dependencies if the
kernel-suspend2-2.6.18 packages were to be removed.

I'm relatively certain the problem is the failure of the 2.6.19 kernels
to provide "kernel" as I said, and demonstrated, earlier.  Not a yum
problem. (e.g. "a severe bug")  See below...

"kernel" is provided for 2.6.18-1.2868_1.fc6.cubbi_suspend2

Ditto for 2.6.18-1.2869_1.fc6.cubbi_suspend2

Now for the 2.6.19 stuff:

No "kernel" provided by 2-2.6.19 suspend2 kernels.

Example from a system with standard, rather than suspend2 kernels:

[root at ping0 ~]# rpm -q kernel
kernel-2.6.19-1.2895.fc6
kernel-2.6.19-1.2911.fc6
[root at ping0 ~]# rpm -q --provides kernel | grep "\.19"
kernel-i686 = 2.6.19-1.2895.fc6
kernel = 2.6.19-1.2895.fc6
kernel-i686 = 2.6.19-1.2911.fc6
kernel = 2.6.19-1.2911.fc6

These, unlike the suspend2 kernels, provide "kernel".

And at the next level

[root at ping0 ~]# rpm -q --whatrequires gnome-volume-manager
gnome-session-2.16.3-1.fc6

These are the packages that are problematic for both yum and rpm on
attempts to remove the 2.6.18 suspend2 kernels.  QED  :-)

I can try smart tomorrow, but can't believe that it will make any
difference.
