Is it possible to compile a 64-bit application against 32-bit libraries  |

no.
You can't link 64bit exe to 32bit so files. (You can't do the reverse either.) |

Canon released some drivers (sourcecode + a few 32-bit libraries)
I don't run AMD64, but some who tried my canon-ebuild do. So I don't know much about 64-bit issues.
Is there any workaround? Something like a 64-bit wrapper around 32-bit libraries? |

| Is the driver 64bit native? Need to really provide more information before people can help. |

The problem with more information is, that I don't know much more. I'm just asking to help someone else. 
What do you mean by "64bit native"?
Does the following help? It's the Portage-Output from someone having trouble with my ebuild.

"libcnbpcmcm221.so" is beeing shipped by canon along with the sourcecode. But 32-bit. (And I don't have any problem on my 32bit AthlonXP). |

| 64bit native means was the driver designed for 64bit operability only. But what I read from your recent post is that you are asking whether the 32bit release Cannon driver can be built on 64bit AMD64. Well I would imagine that if somebody has enabled 32bit emulation in their 64bit install it should compile okay, as long as the dependancies are available. |
