Without some information about what FreeBSD is seeing, it's impossible
to say what controller you really have and why it is being detected how
If you can get to the point where you can run "pciconf -l -v" (fixit
shell?) you can see exactly what information FreeBSD sees to identify
the device. You can then compare that to the IDs that the amr and mpt
drivers latch on to. (The cvs web tree would have that, or you could
try posting back that info so that someone with 6.1 could check).
It wouldn't be unheard of for Dell to have *changed* which chips they
use for a PERC 4/IM; or perhaps there is a documentation error.
But if the mpt driver is latching on to the device it must be because it
thinks it should. If the amr driver does not recognise the device then
what you are suggesting wouldn't work, even if it were possible. Unless
there is a bug, then, in general, only one hardware driver will ever
recognise any specific device/chip.
If it really is the mpt driver which should be loaded, then, as Lowell
says, asking the driver author (or trying hardware@) would be your best bet.
Did you try google for "Dell 1855 Freebsd"?
