installed Fedora Core 5 but have questions

["Raul A. Gallegos" <raul@asmodean.net>]

OK. After a short-lived experience with GRML I relize it was not for me. 
So I figured I'd go back to Fedora Core. I was previously using 3 and 
figured it was time to use 5.

I installed 5 via telnet so am faced with no speakup modified kernel. 
I've downloaded the kernel rpm from speakupmodified.org. The one which 
is currently on my system is:

kernel                  i686       2.6.17-1.2139_FC5  

So I downloaded the kernel I found on the ftp site which appears to have 
the same version. The name of the rpm is

kernel-2.6.17-1.2139_FC5spk.i686.rpm

When I try to install it though I get an error about the gpg key. Output 
is below.

kernel                  i686       2.6.17-1.2139_FC5  installed

Public key for kernel-2.6.17-1.2139_FC5spk.i686.rpm is not installed

So, first question is how do I install getting past this error?

Second question is what would be the correct syntax in removing the 
original kernel installed by fc5 which is 2.6.15. I was looking in 
/boot/grub/grub.conf and I see that one in there as well.

Third question. Am I correct in assuming that once the speakup modified 
kernel is installed I still need to make the initial ram disk so that it 
knows which synthesizer I'm using?

Thanks and FYI. I've read the various posts on the speakup archives 
especially messages from Janina and Stephen but 
none of them have mentioned the rpm and key bit. Many thanks in advance 
to anyone who can help.
