rpm db destroyed? removing old FC4 kernels

[Patrick Steiner <patrick steiner a1 net>]

hi,

today i noticed, that there are old FC4 kernels on my FC5 system (rpm 
-qa | grep kernel). but if i do an rpm -e kernel-devel-2.6.14-1.1656_FC4 
my FC5 box doesnt to very much. if i take a look to /boot or 
/lib/modules to old kernels are not available. is my rpmdb destroyed? 
how can i repair this.

i have updated my fedora system from FC4 to FC5 via cd.

regards,
patrick
