dkms + megaraid_sas and kernel update

[Rainer Traut]

Hi all,

sys: el5 x86_64 on PE2950III,
with dkms from dell repo.

After a kernel update from 2.6.18-53.1.14.el5 to 2.6.18-53.1.19.el5
I see that none of my dkms installed drivers are used by the new kernel:

# dkms status
megaraid_sas, v00.00.03.16, 2.6.18-53.1.14.el5, x86_64: installed 
(original_module exists)

megaraid_sas, v00.00.03.16, 2.6.18-53.1.19.el5, x86_64: installed-weak 
from 2.6.18-53.1.14.el5

# dmesg |grep bnx

# dmesg |grep mega

How can I fix this?
Where's the sense in dkms if I have to manually install after a kernel 
update?

Thx
