The answer is: the more recent your system the less a problem.  You
should be able to use Edgy or (in a month) Feisty on that system without
the command line argument and without any problems.

I am not certain about Dapper but I believe it doesn't have support for
ATAPI devices in the kernel.  I don't have the relevant hardware to be
certain, sorry.

I know that on most RPM based distributions grabbing and installing a
random RPM from the Internet is pretty common.  Under Debian and Ubuntu
that isn't really the case.

When you find a third party who you really /need/ packages installed
from -- and that shouldn't happen often -- they generally publish a
repository that works with apt.

So, to do this you normally add the appropriate entries to
/etc/apt/sources.list (through your GUI of choice, or by hand) and then
install the package just like every other.

...or, more efficiently, as 'dpkg -l xserver*'

Er, quoted if you had any files in the current directory starting with
'xserver' -- passing a glob to dpkg -l is matched as you would expect.

See also the manual page for details on how to get a format other than
the default for the package list.

Nope.  Well, not really, anyway.  There might be a better solution to
the problem that you /think/ the equivalent of 'rpm -qa' is the solution
to, but not to the core "list packages" task.
