There's actually a bunch of reasons a kernel can be tainted.

IIUC that's an array of bit flags, and that value means you've had a previous 
kernel warning at that point according to:

https://www.kernel.org/doc/Documentation/sysctl/kernel.txt

# tainted:
#
# Non-zero if the kernel has been tainted.  Numeric values,
# which can be ORed together:
#
[...]
# 512 - A kernel warning has occurred.

Best of luck!
