I setup an armel (softfp) version of Debian Wheezy in chroot on a Huawei 
u8150 phone. Its /proc/cpuinfo shows the following:

Processor       : ARMv6-compatible processor rev 2 (v6l)
BogoMIPS        : 121.80
Features        : swp half thumb fastmult edsp java
CPU implementer : 0x41
CPU architecture: 6TEJ
CPU variant     : 0x1
CPU part        : 0xb36
CPU revision    : 2

It looks like it has ARM1136 (RPi B+/Zero has 1176) that should be the 
lowest model with ARMv6 support.

I haven't yet build jdk on it, but compilation of simple programs (tried 
detect.c mentioned before) works fine on it.
