Bug#410817: linux-image-2.6.18-3-686: new megaraid driver fails to detect logical drive

Try to use module megaraid_mbox, instead of module megaraid.
Ok, I reboot with 2.6.18-3 and:
root@clap:~# rmmod megaraid
root@clap:~# rmmod megaraid_mbox
root@clap:~# rmmod megaraid_mm
root@clap:~# modprobe megaraid_mbox
root@clap:~# lsmod |grep megaraid
megaraid_mbox 29168 0
megaraid_mm 10560 1 megaraid_mbox
scsi_mod 124168 2 megaraid_mbox,sd_mod
dmesg says:
megaraid: detaching device 0x101e:0x1960:0x1028:0x0511

i.e. drive still missing.
Then:
rmmod megaraid_mbox
rmmod megaraid_mm
root@clap:/usr/src/linux-2.6.18.2/drivers/scsi# lsmod|grep megaraid
megaraid 35880 0
scsi_mod 124168 2 megaraid,sd_mod

megaraid cmm: Unregistered one adapter:0x110

i.e. the megaraid driver doesn't appear to find the hardware. The
messages in dmesg appear to come from megaraid_mbox (have verified this
by looking in the source).
Indeed this makes sense, my card has PCI ID 101e:1960, and the legacy
megaraid driver lists:
alias: pci:v0000101Ed00009010sv*sd*bc*sc*i*
alias: pci:v0000101Ed00009060sv*sd*bc*sc*i*
alias: pci:v00008086d00001960sv*sd*bc*sc*i*
but megaraid_mbox lists:
alias: pci:v00001028d0000000Esv00001028sd00000123bc*sc*i*
alias: pci:v00001000d00001960sv00001028sd00000520bc*sc*i*

so my card will not be picked up by the legacy driver.
The (legacy) megaraid driver includes the 101e:1960 pci id, but this has
been removed in the etch kernel. I will try hacking the pci id into the
legacy megaraid driver.
