hot new laptop for ubuntu 10.04, and detecting DDR3 memory?

[Robert P. J. Day]

  in aid of deciding whether or not to buy this as my new primary work
system:

i popped over to the store yesterday, dropped in ubuntu 10.04 desktop,
brought it up live and everything seemed to work.  the stock nouveau
drivers supported the native res of 1600x900 just fine, which was my
major concern.  bit disappointing that something advertised as an
"entertainment notebook" didn't have a blu-ray drive, especially when
a lower model of hp dv7 *did* but i can live with that.

  only curiosity i had was to verify that memory was, in fact, DDR3,
not DDR2.  i'm convinced it is from the spec sheet, but is there a way
to verify that on a running system?  i popped into "lspci" and a
number of other utilities i know, but couldn't nail that down.  can it
be done?

  oh, and what will tell me that the HD is 7200 rpm, rather than just
5400 rpm?  again, the utilities i know about didn't tell me that.  is
there a way?  thanks.
