Two possibilities:
1)
gpg --list-packets hauke__0x1a571df5.asc
[...]
:public sub key packet:
version 4, algo 1, created 1352000413, expires 0
pkey[0]: [2048 bits]
pkey[1]: [17 bits]
keyid: 486B17AB3F96AD8E
:signature packet: algo 1, keyid BF4B8EEF1A571DF5
version 4, created 1352000413, md5len 0, sigclass 0x18
digest algo 2, begin of digest c1 78
hashed subpkt 2 len 4 (sig created 2012-11-04)
hashed subpkt 27 len 1 (key flags: 02)
[...]
Subpacket class 27 is the key capabilities.

First octet:
0x01 - This key may be used to certify other keys.
0x02 - This key may be used to sign data.
0x04 - This key may be used to encrypt communications.
0x08 - This key may be used to encrypt storage.
0x10 - The private component of this key may have been split
by a secret-sharing mechanism.
0x20 - This key may be used for authentication.
0x80 - The private component of this key may be in the
possession of more than one person.
2) You import the key but direct it to a different keyring, see
--keyring
--secret-keyring
--primary-keyring
--no-default-keyring
