Subject: EXPORT_SYMBOL not mandatory in 2.4.x?

Hi,

1) I'm using two 2.4 based kernel modules. The first module defines a
symbol but does not EXPORT_SYSMBOL() it. Would my second module be
able to use that symbol? In 2.4? In 2.6?

2) Also, in 2.4, is it OK if I start using my device memory before
request_mem_region()?

Thanks,

Rick
