Almond and Palm without the "l" sound very off around here, and I've never heard a native pronounce either of those without the "l".  But maybe some do--they're not the most common words.  "Half" is usually pronounced the same as "have" and to "halve".  Other words such as "balm" all have the "l".  I didn't understand what someone wanted when she asked for the "lip bomb".  (she was from Utah.)
How do you pronounce "palm"
    *and by native I mean native of this area, not a native English speaker.
    <<The spelling pronunciation form ["Q:U~mI~:nd] is used for "almond" here, unlike "palm" where the non-spelling pronunciation form is most prevalent here.>>
That pattern applies to me as well. I use l-less pronunciations for:
palm: ["p_hAm]
balm: ["bAm]
But I use a with-L pronunciation for:
almond ["A5m@nd]

    I can say palm either with or without the L.  Usually it's got a hint of the L without being a full L, if that makes sense.  A little more than I would put in calm, which has no L for me.  I don't think you can accurately say that I have any particular regional accent, as I've lived all over the US.  
The only place I've ever heard almond said without the L is in northern California, where it struck me as a weird regional thing.

    I live in Southern California, and I have never heard "palm" pronounced without the L (unless it was being said by someone with a really heavy foreign accent). So, I don't know where people are getting the idea that the L-less pronunciation is regional of the Southwest.
Meesh.

I have the "l" in calm as well. Kahm is understandable though, because it's not like "balm" that can be confused with "bomb".

Do you actually use a close back unrounded vowel in "palm"?

    I do pronounce the l.  I think that my pronunciation would be closest to [pOlm].  I'm from Minnesota.

Yay! Finally another "l" pronouncer! We l-pronouncers are much cooler than ordinary folk! :)

    "I have the "l" in calm as well. Kahm is understandable though, because it's not like "balm" that can be confused with "bomb". "
I pronounce balm [bOlm], but bomb [bam]. It seems that the l helps prevent the O-->a.

So is that the Northern cities vowel shift?
