[br-KernelNewbies] Chamada a função identify_cpu() da API

Bom dia,
Estou tentando recuperar algumas informações do hardware através da
API do kernel. Utilizo C, Não posso fazer chamadas system de nenhum
tipo, por ser um método menos seguro do que chamar a API diretamente.
Já consegui recuperar informações do HD e da placa de rede. Porém, a
bios e a CPU estou ainda com problemas.
A compilação [1] do arquivo [2], resulta em uma série de erros [3] nos
.h do kernel. As causas que especulo para estes erros [3] são:
- Versões das minhas libs e do gcc estarem em conflito de alguma forma.
- Falta de includes necessários para suprir algumas funcionalidades.
- Pacotes -dev estarem corrompidos
Estou usando o debian etch devidamente atualizado.
Quando estava tentando recuperar informações da bios, tive problemas
similares, No momento não estou com o código usado para testar essa
API.
Gostaria de saber de vocês:
- Existe alguma maneira de recuperar informações da bios e da CPU de
alguma outra forma?
- Alguém sabe como solucionar estes erros? ou tem algum comentário a
fazer a respeito?
Rúben
