Hmm according to the ATMega-32 data sheet you can specify a mask.

"
 The Break Point Unit implements Break on Change of Program Flow, Single Step
 Break, 2 Program Memory Break Points, and 2 combined Break Points. Together, 
the 4
 Break Points can be configured as either:
 •  4 single Program Memory Break Points
 •  3 Single Program Memory Break Point + 1 single Data Memory Break Point
 •  2 single Program Memory Break Points + 2 single Data Memory Break Points
• 2 single Program Memory Break Points + 1 Program Memory Break Point with mask
  (“range Break Point”)
• 2 single Program Memory Break Points + 1 Data Memory Break Point with mask
  (“range Break Point”)
"
I haven't actually tried though.
