well, ill be... my mistake: should be:

alias block-major-58 lvm-mod
post-install block-major-58 /sbin/vgscan && /sbin/vgchange -a y
pre-remove block-major-58 /sbin/vgchange -a n
alias char-major-109 lvm-mod
post-install char-major-109 /sbin/vgscan && /sbin/vgchange -a y
pre-remove char-major-109 /sbin/vgchange -a n

The alias for the block-major-58 and char-major-109 are in most of the 
lvm howtos i've seen, and i cant readliy give an explaination. as for 
the post-install and pre-remove, I added that because I was having 
problems with the default redhat 7.3 init scripts, and to me, editing 
/etc/modules.conf was easier than editing the init scripts

now to go correct that file on my server ;-)
