u32 is ALWAYS 32 bit!!! u32* is, as all pointers are, 64 bits.
For numerics, it's "long" that modifies its length! (32 on i386 and 64 on amd64, alpha and itanium).
Taken from alpha's <asm/types.h>
typedef unsigned short u16;
typedef unsigned int u32;
typedef unsigned long u64;
These are standard sizes for unix on 64bit systems. If the compiler code is issuing different sizes, there is a problem in its includes (like asm/types.h). A quick prog that printfs some sizeofs could shed light on the subject.
Once again, be careful with eventual chunks of code inside #ifdef X86 that may assume long to be 32bit.

The method used to transmit mail messages across the Internet, SMTP, is not reliable, so anyone can send a mail pretending to be someone else. Current mail spreading virus and worms use this to attempt to make it look like its messages are from a trustworthy source. Only in the presence of a valid digitally signed message can someone assume the source was not forged and the content has not been tampered with. Help making internet mail more secure by adopting and recommending digital signatures in mail messages.

I guess the firmware is not loaded correctly.
Please revert av7110.c to the state from CVS (or from 1.1.0), and apply
the patch below:
(u32 is 64 bit on amd64, but AFAIK uint32_t should always be 32bit
according to ISO C99)

If that doesn't fix it (because uint32_t is 64bit...) we need to do
some more work.
If it doesn't work, can you run the following program and post its
output:
-----
#include <stdio.h>
#include <stdint.h>
int main()
{
printf("%u\n", sizeof(uint32_t));
return 0;
}
